Question

With a practical example explain the following statement
“Torque is directly proportional to the rate of change of angular momentum”.

Answer 1

Explanation:

• Newton's 2nd law says that External Force is directly proportional to the rate of change of momentum. Similarly, external torque is directly proportional to the rate of change of angular momentum. So if angular momentum is conserved i.e., the rate of change of angular momentum is zero then external torque is zero.
