Utilizing the concept and definition of inertia, mass, velocity, and acceleration, the concept of momentum was presented as the product of mass and velocity. A change of momentum is brought about by a change in velocity, which is acceleration (mass generally remains constant in velocity change). A force is needed to bring about a change in velocity, which brings about a change in momentum. A change in momentum is termed an impulse, which is dependent on a force and the time the force is applied. Impulse is defined as force x time applied or ft. Change in momentum is delta mv, therefore impulse = change in momentum, or ft = delta(mv). Demonstrations using model cars and trucks was used to show the change in momentum with the change in time the force was applied.
