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, in 2 sentences
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 acts on an object and causes a displacement in the direction of the force. In this case, the force of gravity acts vertically downwards, while the motion of the puck is horizontal, perpendicular to the force, resulting in no displacement in the direction of gravity and therefore no work done.
