HowStuffWorks explains that levers work by reducing the force needed to move weights. They achieve this by increasing the distance through which the required force acts. For instance, a 1-kilogram force that acts through... More »

A lever is a simple machine, and it only consists of two material components and two work components. A lever can be made with a beam, or solid rod; a fulcrum, or pivot point; an input force, or effort; and an output for... More »

Third-class levers have an input force, a fulcrum and an output force. The placement of the fulcrum, input and output forces of the lever determines its type. More »

Waterwheels work by using the force of water flowing or falling onto pedals inside the wheel to turn it. This rotation then allows the shaft of the wheel to transmit the energy created to move machinery. More »

An inclined plane works by reducing the amount of force needed to lift an object from a lower point to a higher one. The inclined plane is normally a flat surface that extends from the lowest point up to the highest, whi... More »

Aerodynamics is a term that describes how force affects objects that move through air. Aerodynamics involves lift, weight, thrust and drag. The shape of an object and its weight affect its lift, and objects have an easie... More »
