Question

According to the law of conservation of momentum,when two objects collide in the absence of outside forces,what?

Answer 1

The objects have the same momentum before and after they collide.

I just took the test and this is the answer.

Good luck!

Answer 2

According to the law of conservation of momentum, when two objects collide in the absence of outside forces the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision. This is because the momentum lost by one object is equal to the momentum gained by the other.
