A lever is a simple machine that changes the distance the force is applied over. It is helpful by since the force is applied over distance you can lift things. One example of this machine is a seesaw and a boat paddle. If we did not have this machine on a seesaw we would stay balance. Levers are devices that increase the force you use them with. Each lever has three main parts: the fulcrum, resistance arm, and effort arm.

Like using a crowbar. The longer the lever the more force you get at the other end.
