Question
Consider an isolated system moving through empty space. The system consists of objects that interact with each other and can change location with respect to one another. Which of the following quantities can change in time?
- The angular momentum of the system
- The linear momentum of the system
- Both the angular momentum and linear momentum of the system
- Neither the angular momentum nor linear momentum of the system
The correct answer is: Neither the angular momentum nor linear momentum of the system
As long as no net external force, or torque, acts on the system, the linear and angular momentum of the system are constant.
