Question

What units are use for expressing rotational velocity

Answer 1

rad/s

Step-by-step explanation:

The angular or rotational velocity of an object refers to the velocity of rotation of that object around a specific point or center per unit time.

While the angle an object makes while rotating around a point is measured in radians, the time the object spends rotating is measured in seconds.

Hence the unit of rotational velocity is radians per second or rad/s.

Answer 2

Answer:rads/s

Or radians per seconds

Step-by-step explanation:

A

Rotational velocity is the rate of velocity at which an object or a particle is rotating around a center or a specific point in a given time period. It is also known as angular velocity. Rotational velocity is measured in angle per unit time or radians per second (rad/s). The rate of change of angular/rotational velocity is angular acceleration.
