Q: What is the effect on the angular momentum of a system if an external torque is applied?
Solution: An external torque changes the angular momentum of the system.
Steps: 5
Step 1: Understand what angular momentum is. It is a measure of how much motion an object has while rotating.
Step 2: Know what torque is. Torque is a force that causes an object to rotate.
Step 3: Recognize that when no external torque is applied, the angular momentum of a system remains constant.
Step 4: Learn that when an external torque is applied to a system, it can change the angular momentum.
Step 5: Conclude that the effect of an external torque is to increase or decrease the angular momentum of the system, depending on the direction and magnitude of the torque.
