Angular Acceleration on a spinning wheel
Think about the situation described below. A number of questions based on this situation are posed afterwards, each having 2 possible responses (FALSE or TRUE). We'll do some (but probably not all) of these questions in the lectures when you will all be asked to vote on which answer you think is correct. (Soon afterwards, you'll be able to see your responses, and those of the whole class at EVAF.)

to signal TRUEThe magnitude of the acceleration of a point on a spinning wheel is
increased by a factor 4 (and direction kept constant) if:
- the angular velocity is increased by a factor of 4 and the angular acceleration is not changed
- the angular velocity and the angular acceleration are each increased by a factor of 2
- the angular velocity is increased by a factor of 2 and the angular acceleration is increased by a factor of 4
