Asked by Katelyn
If the momentum of one object changes in a system that is subject to no net external force, what else must happen?
1) Collisions with other objects will change its momentum back.
2) The momenta of the other objects in that system change in the same way.
3) The momenta of the other objects in that system are not necessarily affected.
4) The momenta of the other objects in that system change to cancel out the first change.
5) The momenta of the other objects in that system are necessarily not affected.

The total momentum of the system can not change if there is no external force. Therefore 4
