alleryStart learning →In which unit is angular velocity expressed?
AMetres per second
BNewtons per metre
CRadians per second
DDegrees per metre
Answer & Solution
Correct answer: C. Radians per second
1. Angular velocity is defined as a rotation angle divided by the time taken.
2. The angle is measured in radians and the time in seconds.
3. So the unit of angular velocity is radians per second.
4. Metres per second belongs to linear velocity, which is a different quantity.
