Why does the force of gravity do no work on a hockey puck sliding across the ice into the goal? Make sure to include the words force, gravity, work and motion in your audio response
The force of gravity does no work on a hockey puck sliding across the ice into the goal because work is only done when a force causes an object to move in the same direction as the force applied. In this case, the force of gravity acts vertically downward, while the motion of the hockey puck is horizontal along the ice. Since the force of gravity and the motion of the puck are perpendicular to each other, no work is done. Work is defined as the product of the force applied on an object and the displacement of that object in the direction of the force, and in this situation, there is no displacement of the puck in the direction of the gravitational force. Thus, the force of gravity does not contribute to the motion of the hockey puck sliding across the ice into the goal.
