Effective collision -- a collision between two reactants with the correct orientation and with sufficient energy to overcome the activation energy barrier (6.9) Show all terms that begin with the letter:
Minimizing Impact Force. The process of minimizing an impact force can be approached from the definition of the impulse of force: If an impact stops a moving object, then the change in momentum is a fixed quantity, and extending the time of the collision will decrease the time average of the impact force by the same factor. This principle is applied in many common-sense situations: 1  If you jump to the ground from any height, you bend your knees upon impact, extending the time of collision and lessening the impact force. 2  A boxer moves away from a punch, extending the time of impact and lessening the force.
