What does newton's third law say about why momentum is conserved in collisions?

A. Equal forces act in equal times, so the change in momentum for both objects must be equal.

B. Unequal forces act in unequal times, so the change in momentum for both objects must be equal.

C. Unequal forces act in unequal times, so the change in momentum for both objects must be unequal.

D. Equal forces act in unequal times, so the change in momentum for both objects must be equal.

I took the test and can confirm that the answer is A.

Jared · Answer 2

For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
