Introduction
Kinematics: motion in one and two dimensions
Dynamics
Work and energy
Rotational motion
Linear and angular momentum
- Linear momentum
  - Ex: tennis ball (an elastic collision)
  - external and internal forces in a collision
  - \( p_{\rm system} = \mbox{const} \), is a separate conservation law
  - Ex: two skaters (c.o.m. does not move)
  - Ex: an exploding shell (c.o.m. keeps on going)
  - elastic collisions in 1D (C.o.K.E. + C.o.M.)
  - Ex: billiard balls, ball against the wall, a golf club
  - inelastic collisions in 1D (only C.o.M.)
  - Ex: a ballistic pendulum
- Angular momentum
  - angular momentum, \( L = I \omega \)
  - conservation of angular momentum
  - Ex: a figure skater's spin
  - vector nature of \( \vec{L} \) and \( \vec{\tau} \)
  - precession and gyroscopes
