Work, Energy, and Power

Work, Energy, and Power. Work. What is Work and Energy?. Energy(E)- the ability to do work Work (W)- A change in energy (?E) or the product of Force and distance (d) W= Fd Work is only being done when components of the applied force are parallel to the displacement

Work and Energy

Work and Energy. Work. In science, commonly used terms may have slightly different definitions from normal usage. The quantity work , is a perfect example of this. Work Definition. Work = Force x Distance W = Fd Thus, work depends on force applied, and distance moved. Example of Work?.
