Question

what does the law of the conservation of momentum state?
when two objects collide, they will keep their initial speeds.
when two objects collide, the systems momentum changes.
when two objects collide, they will each keep their initial momenta.
when two objects collide, the systems momentum remains the same.

Explanation:

The law of conservation of momentum states that in the absence of external forces, the total momentum of a closed system remains constant. When two objects collide, the sum of their momenta before the collision is equal to the sum of their momenta after the collision. This means the system's momentum remains the same.

Answer:

When two objects collide, the system's momentum remains the same.
