Key Concepts

Impulse and Momentum

The impulse experienced by an object is the product of the force applied and the time over which it is applied, and it results in a change in momentum. In collision scenarios, even though the change in momentum might differ due to differing masses, the impact force (as related to impulse during the collision) experienced by both objects remains equal, in accordance with Newton's Third Law.

Newton's Third Law

Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that when two objects collide, the force that one object exerts on the other is exactly equal in magnitude and opposite in direction. The law applies regardless of the masses of the objects involved, ensuring that both vehicles experience forces of equal magnitude during the collision.
