In a vehicle collision the longer it takes to dissipate kinetic energy the force of impact?

In a vehicle collision, the force of impact is directly related to the rate at which kinetic energy is dissipated. The longer it takes for the kinetic energy to dissipate, the lower the force of impact experienced by the vehicle occupants. This is why vehicles are designed with crumple zones and other safety features to extend the duration of the collision and reduce the force transmitted to the occupants.
