Pneumatic circuit following devices operate using compressed gases, but are not normally thought of as being pneumatic circuits: Pneumatic circuit A pneumatic circuit is an interconnected set of components that convert compressed gas (usually air) into mechanical work. In the normal sense of the term, the circuit must include a compressor or compressor-fed tank. The circuit comprises the following components: In general, based on the application, a pneumatic cylinder is usually a single acting cylinder, where there is a single port in the cylinder and where cylinder extension is done by compressed air and retraction by means of open coiled spring.

Potential energy to the gravitational potential energy, thus The more formal definition is that potential energy is the energy difference between the energy of an object in a given position and its energy at a reference position. Potential energy is closely linked with forces. If the work done by a force on a body that moves from "A" to "B" does not depend on the path between these points (if the work is done by a conservative force), then the work of this force measured from "A" assigns a scalar value to every other point in space and defines a scalar potential
