LECTURE NOTES

- Circular Motion 
- Gravity

PROBLEM SOLVING

- Circular Motion
36 interactive problems with hints and detailed solutions.

- Gravity
10 interactive problems with hints and detailed solutions.

KEY ITEMS:

• Students often think of centripetal force as a special kind of force. To
avoid this, I always ask my students to write down what force causes
circular motion i.e. friction, tension, gravitational, normal, etc.

• Students should never label 'centripetal force' on a free-body-diagram.
