I had a severe concussion in a car accident recently, with a 3-inch laceration in my scalp and internal bleeding. A longer period of contact allows kinetic energy to be dissipated over a prolonged period, resulting in less damage to the tissues than an equally forceful impact with dispersion of energy over a brief period.

The brain can be damaged by trauma in two ways. If the lesions occur relatively close to the time of death, they may ooze bloody fluid, imparting a hemorrhagic appearance that mimics antemortem abrasion, as seen in the images below. Another reaction is where the object causes an inward bending of the skull resulting in crushing of the outer table and diploe with fractures radiating outwards.
