There are three types of levers: first-class, second-class, and third-class. The difference between the three classes depends on where the force is, where the fulcrum is, and where the load is.

Use levers to magnify forces. A lever is a mechanism that can be used to exert a large force over a small distance at one end of the lever by exerting a small force over a greater distance at the other end.

Levers are the most basic machines which are used to do some work with minimal effort. A lever amplifies an input force to provide a greater output force, which is said to provide leverage.
