MOM – B - Impulse and Change of Momentum
... Mountain climbers use nylon safety ropes due to their tendency to stretch considerably under stress. Use physics to explain why. The safety ropes are intended to halt the climber's motion if s/he begins to fall. It exerts an impulse on a falling person to cause a momentum change. Being made of nylon ...

Newton`s Laws of Motion
... In racket and bat sports, hitters are often encouraged to follow-through when striking a ball. High speed films of the collisions between bats/rackets and balls have shown that the act of following through serves to increase the time over which a collision occurs. This increase in time must result ...
