A lever is a simple machine that uses variable distance to multiply force, or to redirect existing forces. With a lever, the force exerted by gravity on a weight can be used to lift another weight. By varying the distance between a lever's ends and its fulcrum, a heavy object can be lifted a short distance by a smaller force moving a longer distance.
A lever is a simple device used for magnifying a force, a lever consists of a beam or rod & a fulcrum around which the rod can pivot. When the rod is arranged so that the fulcrum is not at the middle, a force applied to the longer arm will produce a bigger force at the shorter arm. The bigger the difference in arm length, the bigger the difference in the force produced.
The disadvantage is that the long arm needs to be moved a bigger distance to move & a shorter distance for the smaller arm. Levers are very widely used, for example; when someone uses a bottle opener to remove the top from a bottle, they are using a lever.
Levers are simple machines that help you move heavy objects. A lever allows a large turning force to be created from a force that is smaller.
The fulcrum and lever is a simple machine that can be used to move objects by multiplying force. This is achieved by sacrificing distance through which the force is applied.

A claw-hammer can be used to lever out nails from a plank of wood.
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
