A lever is a simple machine. Levers make moving things easier.There are two parts of lever the bar and the fulcrum. Another word for the fulcrum is the pivot point. When you use a lever to move things you use less force but if you don't use the lever you use more force. The bar pivots around the fulcrum.
The fulcrum is in the middle of the bar but there is weight on one side so the side withe no weight is in the air and the side with weight is on the ground.
