Fig. 1-1 shows a race car seriously damaged in a car accident.
The damage is caused by the enormous force of the collision. Experience
tells us that a fast car will be more seriously damaged than a slow one
in an accident. It is also apparent that a massive truck will cause more
damage to a lamppost than a light car of the same speed (Fig. 1-2). The
impact force in an accident is somehow related to the mass and the speed
of the vehicles. Fast and massive vehicles will cause more serious damage
than slow and light ones.

lamppost than a car moving at the same speed.
