You drop from 2 floors up and smash into the ground. SPLAT! Your impact time is the very short time when your velocity changes from some value v (just about to hit the ground) to zero (i.e. you are now at the same velocity as the ground). Your contact time is very long and stops until someone scrape you off the ground, i.e. the time you are in contact with the floor.

Zz.
I see now. So what if you have two cars colliding head on and bouncing off each other? would contact time be the same as collision time in this situation?
