Question

body rotate about its axis ...... is required 1. force 2. torque 3. power 4. displacement
​

Answer 1

Answer:

Torque

Explanation:

When a body is free to rotate around an axis, torque must be applied to change its angular momentum. The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.
