Options:

Correct Answer: Angular momentum

Solution:

In the absence of external torques, angular momentum is conserved.

Which of the following quantities is conserved in the absence of external torques?

Which of the following quantities is conserved in the absence of external torques?

Step 1: Understand what a torque is. Torque is a force that causes an object to rotate.
Step 2: Learn about external torques. External torques come from outside forces acting on an object.
Step 3: Recognize that if there are no external torques acting on a system, it means the system is isolated from outside influences.
Step 4: Know what angular momentum is. Angular momentum is a measure of how much motion an object has while rotating.
Step 5: Remember the principle of conservation. In physics, when a quantity is conserved, it means it stays the same over time.
Step 6: Conclude that in the absence of external torques, the angular momentum of the system remains constant.
