Cool What Is The Formula Of Work Energy And Power

Pout is the output power or actual work in watts W.

What is the formula of work energy and power. It is a scalar quantity. Pfrac W t Power is easily derived from the definition of work. Units are Js or W watts.

Work of force F acting on a body can be defined in several ways. The work performed by a constant force acting parallel to the displacement of a body is defined as 44. The work put into an object equals its change in kinetic energy.

For formulas see work done by a constant force parallel to displacement and work done by any constant force and work done by a position-dependent force. Power is defined as the rate at which work is done or the rate at which energy is transfered to or from a system. He also uses a simple example to calculate both work and powerIntro Music AtributionTitle.

It is the rate of doing work or the rate of transferring energy It is denoted by the letter P and its SI. η 100 Pout Pin. The power output of electrical equipment such as light bulbs or stereos is typically advertised in watts.

If under a constant force F the object is displaced through a distance s then work done by the force W F s Fs cos θ.

The amount of energy transferred per unit time or work divided by time. See definition of total mechanical energy. Work Energy and Power.
