What does the law of conservation of momentum state?
What does the law of conservation of momentum state?
- The total momentum of bodies changes with time.
- Momentum can be created but not destroyed.
- The total momentum of bodies in an isolated system remains constant unless an external force is applied. (correct)
- An external force is not required to keep the total momentum constant.
