Work, Energy and Power

Work, Energy and Power. Work. W = Fs W= work F = force s = displacement Whe a force makes an object move, work has been done. Whenever work is done, energy is transferred form one place to another or transformed from one form to another. Units are = 1Nm = 1J(joule). Practice Problem 1.

Energy can change from one form to another without a net loss or gain.

Energy can change from one form to another without a net loss or gain. Energy Notes. Definition of energy: The ability to cause change. Every change involves energy. Energy can be stored, transferred and used. Definition of work: W = Fd (Work equals force times distance)
