Learn how work is the product of force and distance, and how it changes the kinetic energy of an object. Explore the work–energy theorem, which relates the net work done on an object to its change in kinetic energy, and its implications for potential energy and power.
Learn how net work done by the net force on a system equals the change in the kinetic energy of the system. Find the formula for the work-energy theorem and its applications in one-dimensional motion.
Learn about the work-energy theorem, which relates the work done by a net force on an object to its change in kinetic energy. This web page is part of a free textbook on university physics, but it has a glitch and cannot be accessed.
The quantity 1 2 mv 2 1 2 mv 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m m moving at a speed v v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.)
The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy. Learn more. For deeper explanations of the work-energy theorem, see our video work and the work-energy principle.
Learn how to apply the work-energy theorem to find information about the motion and forces of a particle. The theorem states that the net work done on a particle equals the change in its kinetic energy.
