This guide presents the standard scope of the undergraduate algebra-based introductory physics sequence (Physics I–II) as general disciplinary background: mechanics, rotation, fluids, oscillations and waves, thermodynamics, and a closing survey of electricity, magnetism, optics, and modern physics. It explains who takes the course, how its chapters build on each other, how physics courses are honestly graded (your syllabus is the only authority), and a study method built for a problem-based, cumulative course. PassProfessor’s companion program organizes 1,020 original practice questions chapter by chapter against this scope.
Introductory Physics, in one paragraph
Introductory Physics is an introductory physics course. Its standard scope: Measurement, units, and vectors; kinematics in one and two dimensions; Newton’s laws, friction, and circular motion; work, energy, and power; momentum and collisions; rotational motion and angular momentum; gravitation, statics, and fluids; oscillations, waves, and sound; thermodynamics and kinetic theory; introductory electricity, magnetism, optics, and modern physics. The course moves through six broad blocks, from measurement, units, and vectors to the closing survey of electricity, magnetism, optics, and modern physics, and its chapters build on each other — physics builds on itself relentlessly, and a shaky vectors foundation resurfaces in forces, momentum, and fields. This guide presents that scope as general course background: who takes the course and why, how its blocks fit together, how grading honestly works, and a study method built for its structure.
Who takes introductory physics, and why?
Introductory physics sits in several degree paths at once, which is why the same lecture hall holds very different students:
- Life-science and pre-health students take the algebra-based sequence because their programs require physics without requiring calculus-based depth; the course’s breadth — mechanics through modern physics in a year — is the point.
- Biology and general science majors take it as core scientific training, often alongside general chemistry, with which it shares the mathematical habits of unit discipline and multi-step problems.
- Students satisfying a science requirement meet in physics the most problem-driven version of the requirement — the course grades solved problems, not recalled paragraphs, which changes how it must be studied.
Whichever path you are on, the scope of the course itself is broadly the same — the discipline has a settled core, and undergraduate courses teach that core in a recognizable order. Instructors differ in emphasis, depth, and exam style; they rarely differ in what the subject is.
The course, piece by piece
The standard introductory physics course moves through six broad blocks. The table below describes each block’s content as general disciplinary knowledge — this is the background every student in the course is expected to build, whatever textbook their course assigns.
| Course block | What it covers |
|---|---|
| Mechanics I: motion and forces | Kinematics in one and two dimensions; Newton’s laws with friction and circular motion. The block’s real subject is method — free-body diagrams, axis choices, and the constant-acceleration model — because every later topic grades that method. |
| Mechanics II: energy, momentum, rotation | Work and energy, impulse and momentum with collisions, and rotational motion with torque and angular momentum. Two conservation laws join the toolkit, and problem solving becomes model selection: which ledger — forces, energy, or momentum — fits this stem? |
| Gravitation, statics, and fluids | Universal gravitation and orbits in outline; equilibrium of static structures; pressure, buoyancy, and flow in introductory form. A bridge block: shorter, diagram-heavy, and a common place for a self-contained unit exam. |
| Oscillations, waves, and sound | Simple harmonic motion, wave behavior and superposition, standing waves, and sound including intensity and the Doppler effect. Periodic phenomena get their own vocabulary here, and it recurs in the optics survey. |
| Thermodynamics | Heat and temperature, calorimetry and phase change, heat transfer, the ideal gas and kinetic theory, and the laws of thermodynamics with engines. Energy returns in statistical clothing; sign conventions and multi-step accounting are the graded skills. |
| Fields, optics, and modern physics survey | Introductory electricity and magnetism, simple circuits, geometric optics, and the first modern-physics topics — photons, the photoelectric effect, atoms and nuclei. A breadth block that previews the second-year courses rather than closing the subject. |
Three structural facts about the course shape how you should study it:
- Method is the curriculum. Textbooks differ in chapter splits, but all of them grade the same underlying routine — model the situation, draw the diagram, write the governing equation, then compute. Practice that skips the first three steps trains arithmetic, not physics.
- The conservation laws are the hinge. Energy and momentum conservation convert the back half of mechanics from force-chasing into bookkeeping. Students who reach rotation still solving everything with Newton’s second law alone run out of time on every exam.
- Units are a grading rubric in disguise. A large share of lost points in introductory physics are unit, sign, and vector-component errors on setups the student understood. Dimensional analysis catches most of them in seconds — the course quietly tests whether you use it.
How introductory physics courses are graded — honestly
There is no official answer here, and any page that gives you one is inventing it. Introductory Physics has no administering body, no published exam format, no passing standard, and no retake policy, because it is not a licensing exam. Your instructor sets the number and format of chapter tests and unit exams, whether homework, projects, or participation are graded separately, and what the final covers. Your course syllabus is the only authority for all of that, and the first study act of the semester is reading it closely: note the exam dates, the chapters each exam covers, and whether the final is cumulative. What this guide can give you is the discipline’s standard scope (above), a chapter-by-chapter walk through the course (below), and a study method built for a cumulative, chapter-organized course — the things that transfer between instructors.
One more honesty note, because students ask: the components differ, but their logic does not. Homework and chapter quizzes reward steady contact with the material while it is current. Unit exams reward integration across a block of chapters. A cumulative final rewards retention — the willingness to keep early chapters retrievable after the course has moved on. A study plan that only ever serves the next test therefore mis-serves the final by design, which is why the planning section below treats retention as a standing task rather than an end-of-term emergency.
A note on editions, ordering, and local variation
No two sections of this course are identical, and the differences are worth naming precisely so you can discount them correctly. Textbooks divide the same scope differently: a topic that is one chapter in one book is two in another, and closing topics migrate between the end of this course and the start of the next in the sequence. Instructors reorder within that freedom — some front-load the chapters their later coursework needs most, some follow their book exactly. Assessment differs more than content does: one section’s midterm is another’s two unit exams, and project, participation, and homework weights are local decisions all the way down.
What does not vary is the discipline’s core: the scope summarized in this guide, the order in which its ideas depend on each other, and the points where students predictably lose marks. Those are properties of the subject, not of any syllabus. Plan against your own syllabus for dates and weights; plan against this guide for scope, sequence, and trouble spots — and when the two seem to disagree, your syllabus governs your grade while the guide still describes your subject.
How to study for introductory physics
- *Read the syllabus like a contract.* Note exam dates, the chapters each exam covers, whether homework is graded, and whether the final is cumulative. In a problem-based course the assessment map matters more than the reading list.
- *Work the chapter while it is current.* After each lecture block, solve that chapter’s problems while the model is fresh. Physics skill decays faster than physics facts; a chapter left for two weeks must be relearned, not reviewed.
- *Always start with the diagram.* Free-body diagram, axes, knowns and unknowns — in that order, on paper, before any equation. The routine feels slow for two weeks and then becomes the fastest thing you do.
- *Classify before you compute.* Name the governing principle out loud — Newton’s second law, energy conservation, momentum conservation — before touching numbers. Misclassified problems are the leading source of confident wrong answers.
- *Check units and reasonableness on every answer.* Dimensions must match the quantity asked for, and magnitudes must survive a sanity test. Build the check into the solution, not after it.
- *Drill your weakest chapter, not your favorite.* Practice results by chapter show where points are actually leaking. Rotation and thermodynamics are the classic under-practiced chapters; the data rarely lies about it.
- *Simulate before each graded test.* Sit a timed set over exactly the chapters the test covers, in one sitting, without notes. Pacing is a trainable skill, and untimed practice does not train it.
- *Rework missed problems after a delay.* Return to problems you missed two or three days later and solve them cold. Recognition (‘I remember this one’) is not the same as production (‘I can build this solution’), and exams only grade production.
Planning the semester, block by block
A chapter-organized course has a rhythm, and planning in its rhythm beats planning against the calendar alone. The course moves through six broad blocks, from measurement, units, and vectors to the closing survey of electricity, magnetism, optics, and modern physics, and each block changes what good studying looks like.
In the opening block, the work is foundation: new vocabulary, new notation or procedure, and the first habits of the discipline. Study time here should be weighted toward accuracy over speed — slow, checked work that builds the representations everything else will stand on. Errors made carelessly in the first block are the most expensive in the course, because later chapters inherit them silently.
In the middle blocks, the work is integration. Chapters begin to cite each other: techniques combine, distinctions multiply, and exam items stop announcing which chapter they belong to. This is where mixed practice earns its keep — sets that draw from several chapters at once, so the skill being trained is recognizing which tool a problem wants, not merely executing the tool of the week. It is also where most students discover their real weak chapter, usually an early one whose gap only becomes visible when a later chapter spends it.
In the closing block, the work is consolidation under time. The material is mostly familiar; the challenge is retrieval speed and endurance across the full scope. Timed, cumulative practice is the right instrument here, and the correct measure of readiness is a cold solve — a problem answered correctly days after its chapter was last reviewed, without a warm-up set first.
Across all three phases, one habit separates the students who finish strong: a standing review rotation. A short weekly pass over earlier chapters — a handful of items from each, answered cold — keeps the early scope retrievable at trivial cost, and converts the final from a re-learning project into a review. The rotation is deliberately boring. That is what makes it work: it does not depend on motivation, deadlines, or panic, and it compounds quietly from the second week of the term onward.
The chapters, one by one
Chapter 1: Measurement, Units and Vectors. The course opens with the language of physics itself: SI units and unit conversion, significant figures, estimation, and vectors — components, addition, and the dot and cross products in the forms the rest of the course will use. Every later chapter spends this chapter’s skills, and unit analysis remains the fastest error check you own for the whole year.
Chapter 2: Kinematics in One and Two Dimensions. Motion described before it is explained: displacement, velocity, and acceleration, the constant-acceleration equations, free fall, and projectile motion as two independent one-dimensional problems. The discipline this chapter teaches — define axes, list knowns, choose the equation that fits — is the template every problem set after it will follow.
Chapter 3: Newton’s Laws, Friction and Circular Motion. Forces enter: Newton’s three laws, free-body diagrams, weight and the normal force, static and kinetic friction, and uniform circular motion with centripetal acceleration. Most of mechanics is this chapter applied patiently — the diagram is the solution’s skeleton, and exams test whether you draw it before you compute.
Chapter 4: Work, Energy and Power. The energy viewpoint: work done by constant and varying forces, kinetic and potential energy, conservation of mechanical energy, conservative versus nonconservative forces, and power. Energy methods solve in three lines problems that force methods solve in ten — exams reward students who recognize when the energy route is open.
Chapter 5: Momentum, Impulse and Collisions. Impulse and linear momentum, conservation of momentum, elastic and inelastic collisions in one and two dimensions, and the center of mass. Collision problems are bookkeeping problems: the marks go to students who write the before-and-after ledger carefully and keep momentum (a vector) separate from kinetic energy (a scalar).
Chapter 6: Rotational Motion, Torque and Angular Momentum. Everything from translation, rebuilt for rotation: angular position, velocity, and acceleration, torque, moment of inertia, rotational kinetic energy, rolling without slipping, and conservation of angular momentum. The chapter’s skill is translation between the two vocabularies — students who build the analogy table early stop confusing the symbols by midterm.
Chapter 7: Gravitation, Statics and Fluids. Newton’s law of gravitation and Kepler’s laws, the equilibrium conditions for static structures, and the fluid basics — density, pressure, Pascal’s and Archimedes’ principles, and Bernoulli’s equation in its introductory form. Three shorter topics share a chapter in most course organizations; each is self-contained and heavily diagram-driven.
Chapter 8: Oscillations, Waves and Sound. Simple harmonic motion — springs and pendulums, energy in oscillation, resonance — then waves: speed, superposition, standing waves, and sound with intensity, the decibel scale, and the Doppler effect. The mathematics is repetitive by design; the exam skill is matching the situation in front of you to the right standard model.
Chapter 9: Thermodynamics and Kinetic Theory. Temperature and heat, thermal expansion, calorimetry and phase change, the modes of heat transfer, the ideal-gas law and kinetic theory, and the laws of thermodynamics with heat engines and efficiency. This chapter mixes definitions, sign conventions, and multi-step energy accounting — careful bookkeeping, again, is the tested skill.
Chapter 10: Electricity, Magnetism, Optics and Modern Physics. A survey chapter to close the algebra-based sequence: electric charge and fields in outline, simple circuits, magnetism and induction in outline, reflection, refraction, and lenses, and a first look at modern physics — photons, the photoelectric effect, and atomic and nuclear basics. Breadth is the point; depth belongs to the second-year courses.
Depth I: Mechanics in Depth. A second pass over Chapters 1–6 at full exam weight: multi-step mechanics problems that chain kinematics, forces, energy, momentum, and rotation in a single stem. This is where unit exams and finals draw their discriminating questions, and where chapter-by-chapter fluency gets converted into problem selection speed.
Depth II: Waves, Thermodynamics and Fields in Depth. Deeper work on Chapters 8–10’s first half: oscillation and wave systems combined with thermodynamics, and field-and-circuit problems that require two models at once. The set exists because survey chapters are where students under-practice — the facts are fresh, the combinations are not.
Depth III: Circuits, Optics and Modern Physics in Depth. The closing survey topics at depth: circuit analysis with combined resistors, geometric optics with sign conventions held consistently, and modern-physics calculations — photon energy, photoelectric thresholds, and decay arithmetic. Sign conventions and unit discipline decide these items more than insight does.
Applied Physics: Applied Physics Cases. Physics in situated form: vehicles, sports, the human body, weather, and machines, each case asking which model applies before any number moves. Applied items punish formula-grabbing and reward the habit of naming the principle first — the habit that separates rehearsed students from lucky ones.
Synthesis: Integrated Physics Synthesis. Whole-course integration: problems whose stems cross the year’s boundaries — a collision that becomes a spring oscillation, a rotating system that becomes an energy problem. Synthesis work is the rehearsal for a cumulative final, and it exposes exactly which early chapter has gone quiet since its own test.
Where students lose points
Vector components quietly dropped
Two-dimensional problems — projectiles, inclined planes, collisions — fail most often at the setup: a force or velocity left un-decomposed, or a sign convention changed mid-solution. The fix is procedural, not conceptual: components in a table, one convention written at the top of the page, and no improvisation halfway down.
Formula-grabbing under time pressure
Students under time pressure reach for the equation that contains the given symbols rather than the principle that governs the situation. The equations of physics are few and heavily shared — the same symbols appear in the wrong model. Classification first (study step 4) is the specific antidote, and it is trainable by drill.
Rotation treated as translation with Greek letters
Torque, moment of inertia, and angular momentum look like translations of familiar quantities, and the analogy mostly holds — until rolling without slipping and combined translation-plus-rotation energy expose the gaps. The analogy table must be built deliberately, including the places it breaks.
Sign conventions in thermodynamics
Work done on versus by the gas, heat in versus out — thermodynamics items are frequently decided entirely by a convention stated once at the chapter’s start. Students lose these points in clusters. Writing the convention on the page before the first substitution ends most of the losses.
Frequently asked questions
Is introductory physics algebra-based or calculus-based at my school? Both versions exist and follow the same topic order. Algebra-based sections serve most life-science and pre-health programs; calculus-based sections serve physical-science and engineering programs and add derivations and calculus techniques. Your course catalog description and syllabus state which version you are in — check before choosing practice material.
What mathematics does the course assume? Comfortable algebra, basic trigonometry — sine, cosine, tangent and their inverses — and vector components. The algebra-based sequence introduces no calculus; where a calculus-based section would differentiate, the algebra-based course uses the corresponding finite-difference or graphical form.
Why do students find physics harder than its syllabus looks? The topic list reads like a survey, but the grading is in problem production: each exam problem is a small modeling task, not a recall item. Students who study physics the way they study vocabulary — reading and highlighting — meet the gap on the first exam. Worked and reworked problems are the study method the course rewards.
How are physics courses usually graded? There is no standard. Instructors weight chapter tests, homework, laboratory work, and the final differently, and set their own formats — multiple choice, free response, or a mix. Your syllabus is the only authority; read its grading table in the first week.
What is a free-body diagram, and why does every instructor insist on it? It is a sketch of one object with every force acting on it drawn as a labeled arrow. Newton’s second law is a vector equation; the diagram is where the vectors get defined. Solutions started without one fail at the setup — wrong normal force, missing friction, phantom forces — far more often than they fail at arithmetic.
When do energy and momentum methods replace Newton’s laws? Whenever the question asks about speeds, heights, or outcomes rather than accelerations and times. Energy conservation connects states without the path; momentum conservation governs collisions and explosions. Recognizing which ledger a problem wants is the central skill of the mechanics half of the course.
How much laboratory work does the course include? Many sections pair the lecture with a laboratory component, graded separately or folded into the course grade depending on the institution. Lab work is institution-specific — this guide and the companion program address the lecture course’s written assessments.
What is the synthesis layer in the companion program for? Cumulative finals. Synthesis questions chain chapters — momentum into oscillation, rotation into energy — the way final exams do. They are the rehearsal for a test that reaches back to September, and they expose which early chapter needs a refresher before the final.
Should I drill chapters in order or jump to my weak areas? Both, in sequence: follow the course’s order during the term, because later chapters spend earlier ones, and use your results by chapter to target the weak spots the data shows. The order question answers itself once you can see your own chapter breakdown.
How does the textbook selector work in the companion program? You pick your course, then the textbook and edition your class uses; the program maps its bank onto that book’s chapter organization so your drills and simulations carry your syllabus’s chapter numbers.
Is the companion program affiliated with any textbook publisher? No. PassProfessor is an independent study provider; the program is not published, sponsored, or endorsed by any publisher or author, is not branded under a textbook’s name, and contains no textbook text or publisher test-bank material.
Does this guide replace my course’s problem sets? No. Your instructor’s assigned problems are the closest model of your instructor’s exams and come first. This guide supplies the course’s map and method; the companion program supplies additional original practice organized the same way. Neither replaces the syllabus, the lectures, or the assigned work.
When does the companion program open? The 1,020-question bank is built and quality-checked and the program is in final preparation. Join the notify list on the program page and we will email you the day enrollment opens.
Using this guide with the practice program
This guide and the companion Introductory Physics practice program are built to be used together, in a specific order. The guide comes first: read the block map and the chapter walk for the part of the course you are entering, so the scope and the trouble spots are familiar before you practice against them. Forewarned is a real effect in a cumulative course — knowing where students lose points in a chapter changes what you notice while your instructor teaches it.
Then practice in the program’s own rhythm. Drill the chapter you are currently in while it is current, in short sets, and let the chapter-level results tell you the truth about the chapter while repair is still cheap. When a graded test approaches, switch instruments: a timed simulation over exactly the chapters the test covers, taken in one sitting, under the same constraints your syllabus describes. Afterward, return to this guide’s trouble-spot section for the chapters the simulation exposed — the diagnosis there is written for exactly that moment.
Before midterms and finals, widen the lens. Work the integrated material that combines chapters, because cumulative exams are written that way, and re-read the structural facts at the top of this guide: they describe how the course’s parts connect, which is what a final actually examines. If a chapter’s results stay weak after honest drilling, treat that as information about sequence, not effort — in a course built like this one, a stubborn chapter is usually standing on a cracked earlier one, and the repair belongs there.
A last word on what neither this guide nor the program can do. Neither can read your syllabus, attend your lectures, or know your instructor’s emphases — the local facts that decide real grades. Use both as they are designed to be used: as the discipline-level map and rehearsal space that make your own course’s local facts easier to master, week by week, while the semester is still young enough for the work to compound.
