Work Energy Theorem Definition Physics

The work energy theorem can also be applied to an object s potential energy which is known as stored energy when a skier waits at the top of the hill before taking off they have potential.

Work energy theorem definition physics.

If you re seeing this message it means we re having trouble loading external resources on our website. The work energy theorem is useful however for solving problems in which the net work is done on a particle by external forces is easily computed and in which we are interested in finding the particles speed at certain positions of even more significance is the work energy theorem as a starting point for a broad generalization of the concept. 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. For an object traveling at a speed v and with a mass m the kinetic energy is given by.

The physics definition of work is. This definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy. Review the key concepts equations and skills for the work energy theorem. This principle of work and its relationship to kinetic energy is a core mechanical physics concept.

Understand how the work energy theorem only applies to the net work not the work done by a single source.
