Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

Before proceeding, be sure you understand the distinctions among force, work, energy, and power. Force exerted on an object over a distance does work. Work can increase energy, and energy can do work. Power is the rate at which work is done.
Work, Energy, and Power. Tired of Ads? Concepts of work, kinetic energy and potential energy are discussed; these concepts are combined with the work-energy theorem to provide a convenient means of analyzing an object or system of objects moving between an initial and final state.
Work. refers to an activity involving a force and movement in the directon of the force. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. Energy. is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work.
the concept of power. how to calculate the power of a system. Energy is best defined as the properties of an object that enables it to do work. Energy is a scalar and is usually measured in Joules.
Examples of Power. Examples of power are limited only by the imagination, because there are as many types as there are forms of work and energy. (See Table for some examples.) Sunlight reaching Earth’s surface carries a maximum power of about 1.3 kilowatts per square meter \(kW/m^2\) A tiny fraction of this is retained by Earth over the long ...
Power is the rate at which work is done. It is the work/time ratio. Mathematically, it is computed using the following equation. Power = Work / time or P = W / t . The standard metric unit of power is the Watt. As is implied by the equation for power, a unit of power is equivalent to a unit of work divided by a unit of time.
