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 definition can be extended to rigid bodies by defining the work of the torque and rotational kinetic energy.

This video explains the work energy theorem and discusses how work done on an object increases the object’s KE.
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 …
The work-energy theorem states that the net work \(W_{net} \) on a system changes its kinetic energy, \(W_{net} = \frac{1}{2}mv^2 - \frac{1}{2}mv_0^2\).
The work-energy theorem says that this equals the change in kinetic energy: − m g ( y f − y i ) = 1 2 m ( v f 2 − v i 2 ) . − m g ( y f − y i ) = 1 2 m ( v f 2 − v i 2 ) . Using a right triangle, we can see that ( y f − y i ) = ( s f − s i ) sin θ , ( y f − y i ) = ( s f − s i ) sin θ , so the result for the final speed is ...
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.
16 Φεβ 2023 · The work-energy theorem states that the work done on a system is equal to its change in kinetic energy. We can understand where this theorem comes from if we break down work and energy. When work is done on an object, there must be a force causing the object to move.
