How does blunt force trauma affect the severity of injuries?
The severity of injuries inflicted as a result of blunt force trauma is dependent on the amount of kinetic energy transferred and the tissue to which the energy is transferred. The kinetic energy associated with a moving object is equal to one half the mass of that object multiplied by the velocity of the object squared (1/2 mv 2 ). In general, a somewhat lighter object traveling at high speed will cause more damage than a heavier object traveling at low speed. [ 1, 2, 3, 4]

What factors affect the severity of blunt force injuries?
Yet another factor affecting the severity of blunt force injuries is the amount of time the body and the impacting object are in contact. 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.
