Front

How many collisions does one body experience during a car crash?

Back

Three collisions, first between the car and object, next between the body and the car, third between the organs, tissues and bones inside the body.

Front

Impulse

Back

Impulse is the force times the time over which it acts, resulting in a change in momentum.
