Chapter 2 built a foundational toolkit. To go deeper or see different perspectives, these are good resources.
Books — university level
Primary reference for this chapter
- Halliday, Resnick, Krane — Physics, Volume 1, Chapter 2. Our main reference.
- Halliday, Resnick, Walker — Fundamentals of Physics (newer edition, same Chapter 2 structure).
Good parallel texts
- Serway & Jewett — Physics for Scientists and Engineers — same topics with different examples. If Halliday’s style feels dense, this often explains more clearly.
- Young & Freedman (Sears & Zemansky) — University Physics. Slightly gentler exposition at the same level.
- Kleppner & Kolenkow — An Introduction to Mechanics. More mathematically rigorous — vectors from the start, calculus fluent, physicist’s outlook. For students headed toward theoretical physics.
For physical intuition
- Feynman Lectures on Physics — Volume I, Chapter 8: Motion. Spend two or three hours with it. Physics explained as a living subject — not just formulas. §8-2 (Speed) has an outstanding discussion of “what does instantaneous velocity mean?”.

Lecture series
- MIT OCW 8.01 Physics I — Lectures — full mechanics course; Lectures 1-5 cover exactly this chapter. Very high quality.
- Khan Academy — Kinematics — 1D kinematics. High school to early university level.
- Walter Lewin MIT Lectures — Lecture 2 on velocity and acceleration. His “showman” style — live demonstrations at the front of class. Famous and worth watching.
Interactive simulations
- PhET Interactive Simulations (University of Colorado, free):
- Moving Man: position, velocity, acceleration — adjust sliders and observe
- Graphing Motion Lab: x-t, v-t, a-t plots side by side
- Physlets (WebPhysics): simple java/html5 applets
Real experiments
- Free-fall experiment on this site — sliders let you estimate g
- Historical Moon experiment: Apollo 15 hammer-feather drop — practical confirmation of Galileo (in vacuum, everything falls at the same acceleration)
- Redbull Stratos: Felix Baumgartner — jump from 39 km altitude. Real-world example of where ideal free-fall works and where air resistance dominates.
More problems
If §2.8’s 20 aren’t enough:
- Halliday, Resnick, Krane — end-of-Chapter-2 problems (~50 problems)
- Irodov — Problems in General Physics — much harder and more elaborate. A classical reference for the serious student
- 200 Puzzling Physics Problems — a “seems-simple-but-isn’t” collection of thought-provoking exercises
- Physics Stack Exchange — Q&A site, many general-physics questions already answered
Topics this chapter didn’t cover
Chapter 2 was strictly 1D motion. To extend:
- Chapter 3 (next): vectors — the prerequisite for 2D motion
- Chapter 4: 2D motion — projectiles, circular motion, relative velocity
- Chapters 5-6: dynamics — finally “why does motion happen” (forces)
- Beyond Halliday Vol 1:
- Motion with air drag: §2.5 pointed at this; a full treatment requires differential equations
- Relativistic kinematics: when velocities approach the speed of light, Newton’s formulas need correction — special relativity (Einstein 1905)
- Analytical mechanics: Lagrangian/Hamiltonian formulations — not better, but more elegant, essential for complex problems
