impact force


Also found in: Encyclopedia, Wikipedia.

impact force

the force generated at the start of contact or collision. In sport this can be the impact of a jumper as they hit the ground in the long jump. Impact injury can occur in collision with another person or object when the force exceeds the strength and elasticity of the tissues. Includes both fractures and soft tissue injuries.
