The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.

- 7.2: Kinetic Energy and the Work-Energy Theorem
Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
Explain work as a transfer of energy and net work as the work done by the net force. Explain and apply the work-energy theorem.
Use the work-energy theorem to find information about the forces acting on a particle, given information about its motion. We have discussed how to find the work done on a particle by the forces that act on it, but how is that work manifested in the motion of the particle?
Work-Energy Theorem argues the net work done on a particle equals the change in the particle’s kinetic energy. According to this theorem, when an object slows down, its final kinetic energy is …
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.
Learn how to derive the work–energy theorem from Newton's law and the dot product. Understand the definition and units of work and energy, and the difference between work and force times distance.
