One of the great upcoming sports in the olympics is the sport of curling. write a brief essay on the uses of momentum collisions in curling. be sure to discuss the importance of massive stones and of going last.

Law of inertia and conservation of momentum and collisions are part of the curling as a sport art. In curling the puck will continue to travel in a straight line and at constant speed, since the frictional forces on the ice are minimal.This is example of the law of inertia.
When the puck collides with another puck on the ice the collision is said to be elastic. And in elastic collisions the momentum is conserved.
