LECTURE NOTES

- Momentum and Collisions
- Collisions in Two Dimensions

PROBLEM SOLVING

- Collisions
10 interactive problems with hints and detailed solutions.

- Multiple Choice Interactive: Momentum
10 interactive problems with hints and detailed solutions.

KEY ITEMS:

• Students often forget that velocity is a vector and that they should
  take into account the direction of the velocity.

• It is important to reinforce the concept that impulse causes a change
  in momentum not just 'impulse causes momentum'.

• Give examples where impulse is depicted as an area under a curve.
