Work is force applied over distance.
Examples of work include lifting an object against the Earth’s gravitation, driving a car up a hill, and pulling down a captive helium balloon.
Work is a mechanical manifestation of energy and is usually expressed as a KiloJoule (1000 Joules).
The standard unit of work is the joule (J), equivalent to a Newton – meter (N · m). This reduces to one kilogram-meter squared per second squared (kg · m 2 /s 2 or kg · m 2 · s -2 ) in base International System of Units (SI) units.
