Spring (device)

A spring is a flexible elastic object used to store mechanical energy. The most common types of spring are helical spring, coil spring (at left), and leaf spring, and they are commonly made out of steel or brass. (See also shock absorber.)

A belleville spring is a disc shaped spring commonly used to apply tension and also in the initiation mechanism of pressure-activated landmines.

The image at left is a special kind of spring known as a slinky.

In physics, a spring can have potential energy. Hooke's Law of elasticity states that the extension of an elastic spring is linearly proportional to its tension.
