Question

the law of conservation of momentum applies to a collision between two objects that occurs in an isolated system. assuming that the collision between object a and object b occurs in an isolated system which of the following statements are consistent with this law? The total momentum of objects A and B will be the same before and after the collision OR The change in momentum of A will be equal and opposite to the change in momentum of B the law of conservation of momentum applies to a collision between two objects that occurs in an isolated system. assuming that the collision between object a and object b occurs in an isolated system which of the following statements are consistent with this law?

Explanation / Answer

The change in momentum of A will be equal and opposite to the change in momentum of B.

The earlier is not right because there is no exchange of momentum between A and B. Then it is not a collision.

As per definition of collision there should be an exchange of momentum when they approach.
