What this course covers

Physics I: Mechanics is the study of motion and its causes — the foundation every engineer, physicist, and physical scientist stands on. The six units build on each other:

1. Kinematics — describing motion: position, velocity, acceleration, projectiles, and circular paths — without yet asking why things move.
2. Forces — why things move: Newton’s laws, friction, springs, and the free-body diagrams that turn physics into careful bookkeeping.
3. Work & energy — a shortcut around Newton’s laws: work, kinetic and potential energy, and the conservation law that solves in one line what forces take ten.
4. Momentum — collisions and explosions: impulse, conservation of momentum, and the center of mass — the quantities that survive the crash.
5. Rotation — Newton’s laws, spun around: torque, moment of inertia, and angular momentum — everything you already know, in circles.
6. Oscillations & gravitation — back-and-forth motion (springs, pendulums, simple harmonic motion) plus Newton’s gravity, from falling apples to escaping rockets.

The final exam

40 questions sampled proportionally across all six units, in random order — kinematics through gravitation, mixed together the way a real final mixes them. Every answer explains itself; missed questions tell you which lesson to revisit.
