Introduction
Kinematics: motion in one and two dimensions
Dynamics
Work and energy
- Work and energy
  - Ex: three ways of putting a toolbox on a shelf
  - Ex: gravitational potential energy, U=mgh
  - Ex: origin of U is arbitrary: a bobsled
  - Ex: change in U does not depend on path: a swimming hole
  - Ex: friction is a non-conservative force; W_total>W_c.f.
  - Ex: hammer and nail (work-energy theorem: K.E. = ability to do work)
  - Ex: dropping things (conservation of total mechanical energy)
  - Ex: role of friction/tension: a skier, a swimming hole (revisited)
  - Ex: Do you believe in the conservation of energy?
  - power = rate of doing work
Rotational motion
Linear and angular momentum
