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.

Section Key Terms. The Work–Energy Theorem. In physics, the term work has a very specific definition. Work is application of force, f f, to move an object over a distance, d, in the direction that the force is applied. Work, W, is described by the equation. W = fd. W = f d.
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. 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.
The work-energy theorem states that the net work \(W_{net} \) on a system changes its kinetic energy, \(W_{net} = \frac{1}{2}mv^2 - \frac{1}{2}mv_0^2\).
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 …
