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 are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.
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.
This physics video tutorial provides a basic introduction into work, energy, and power. It discusses the work-energy principle, the relationship between work, force, & displacement as well...
In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
Energy. is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work. To do 100 joules of work, you must expend 100 joules of energy. Power. is the rate of doing work or the rate of using energy, which are numerically the same.
Lesson 1: Work and energy. What are energy and work? What is kinetic energy? What is gravitational potential energy? What is conservation of energy? Work and the work-energy principle.
