The following video demonstrates a large pickup truck and a small vehicle colliding. After the crash it is apparent that the small car sustained more damaged than the Ford so it easy to say that the Ford had more force and power which caused the damage. Yet through Newton's Third Law it explains that the same amount of force is exerted. Also in terms of momentum through the equation pi=pf, energy is conserved and transferred but never loses its energy.
