2. explain how newtons 3rd law of motion relates to collisions?

Brief Explanations:

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. In a collision, when one object exerts a force on another (action), the second object exerts an equal - magnitude and oppositely - directed force on the first (reaction). This law helps explain the forces involved in collisions, such as the recoil when two billiard balls hit each other.

Answer:

Newton's 3rd Law states that for every action force during a collision, there is an equal and opposite reaction force. This law describes the interaction forces between colliding objects, where the force exerted by one object on the other is matched by a reaction force from the second object back on the first.
