Introduction
Kinematics: motion in one and two dimensions
Dynamics
Rotational motion
Work, energy, momentum

Work
- Ex: Constant force: ice block
- Ex: Variable force: Slinky Dog
Power

Ex: leaking ship

Kinetic energy and the Work-Energy Theorem

work on an apple
Ex: baseball slide

Conservative Forces

Gravity

Ex:skateboarding ramp

Spring Force

Ex: pinball launcher

Rotational Work and Kinetic Energy

Ex: potter's wheel
Ex: cylinder race

Linear Momentum

Ex: astronaut and satellite

Collisions

Impulse

Ex: Superman and the bullets

1-D Inelastic collisions

Ex: a ballistic pendulum

1-D Elastic collisions

Ex: particle collision

2-D Inelastic collision

Ex: hockey player

Collisions and center of mass
