Learn the definition, derivation and applications of the work-energy theorem, which relates the work done by the net force on a particle to the change in its kinetic energy. The web page also covers the extension of the theorem to rigid bodies and other forms of energy.
14 lis 2013 · Learn how work and kinetic energy are related in physics with this video lesson by David SantoPietro. Watch examples, definitions, and key moments of the work-energy principle.
Learn how the change in kinetic energy of an object is equal to the net work done on it. See examples of work, energy and power in mechanics problems and applications.
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 principle to rotating objects with constant or net torque. Find out how to calculate the kinetic energy of rolling objects and the relationship between angular and linear velocity.
Learn how work is the application of force over distance and how it changes the kinetic and potential energy of an object. Explore the work–energy theorem, power, and examples of work and energy in physics.
Explain and apply the work-energy theorem. Work Transfers Energy. What happens to the work done on a system? Energy is transferred into the system, but in what form? Does it remain in the system or move on? The answers depend on the situation.
