The fulcrum is that point where a lever is fastened to a stable point. Usually it is in the middle of the lever (as when you pry the lid of a paint can) but it can be at the end (as in the case of a bottle opener). When the fulcrum is at the end, the force that results is in the same direction as the force you apply; you lift up on the bottle opener and it lifts the bottle cap up. When the fulcrum is in the middle, the resulting force is in the opposite direction to the force you apply; you push down on the prybar and the paint can lid goes up.

A fulcrum is a point or support on which a lever pivots. It is often used in physics and engineering to describe the point where a lever is balanced.
