Reflect and research
- How can a bicycle move forward? Draw the external forces on the bicycle that are required for the wheels to turn.
- Does conservation of angular momentum play a role in being able to remain upright on a bicyle? If yes, how?
- How does an anti-lock braking system (ABS) provide better breaking for your car? What is the physics behind this?
To try at home
- Describe how you can qualitatively confirm conservation of angular momentum.
Reflect and research
- Propose an experiment to measure the critical angle of an incline, above which a given object cannot roll without slipping, and compare this to a model prediction.
- Propose an experiment to test the conservation of angular momentum of a rotating object.
- Propose an experiment to test whether an object with constant velocity can impart angular momentum to another object.
