AAs the angle turned times the time taken
BAs the angle turned per unit of time
CAs the radius times the angle turned
DAs the time taken per angle turned
Answer & Solution
Correct answer: B. As the angle turned per unit of time
1. Angular velocity measures how fast the angle of rotation is changing.
2. In symbols that is omega = delta theta / delta t, an angle divided by a time.
3. So it is the angle turned per unit of time, measured in rad/s.
4. Multiplying angle by time would give a quantity that grows the slower the body turns.
