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.

This video explains the work energy theorem and discusses how work done on an object increases the object’s KE.
The work-energy theorem states that the net work \(W_{net} \) on a system changes its kinetic energy, \(W_{net} = \frac{1}{2}mv^2 - \frac{1}{2}mv_0^2\).
22 Δεκ 2020 · The work-energy theorem, also called the work-energy principle, is a foundational idea in physics. It states that an object's change in kinetic energy is equal to the work performed on that object. Work, which can be negative, is usually expressed in N⋅m, while energy is usually expressed in J.
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 …
According to this theorem, when an object slows down, its final kinetic energy is less than its initial kinetic energy, the change in its kinetic energy is negative, and so is the net work done on it.
Kinetic Energy and the Work-Energy Theorem. 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. 7.3. Gravitational Potential Energy. Explain gravitational potential energy in terms of work done against gravity.
