Field hockey



In years past when I used to play field hockey, friction and forces were a big part of the game. First of all, some games would be on grass and others on turf. These were two completely different types of games due to the amount of friction the ball and the ground had. On turf, the ball moved much faster due to the fact that the surface is smoother. The ball continues to travel for a longer amount of time on the turf than the grass because the grass has lots of divits and bumps and holes. These spots add resistance to the ball making the game extremely slower.

Also, when hitting the ball, you can tell that the ball is exerting a force on the stick because the stick shakes and vibrates. Since the stick has a larger mass and another force acting upon it (someones hands) it will not move but the ball will. When the ball hits the goal cage, a loud noise is made. This is because of the force the ball is exerting on the wood, but the ball bounces back off the goal cage because of the force the goal is exerting back.

All forces come in equal and opposite pairs and there are no exceptions.
