- 7.4: Work-Energy Theorem
The work W done by the net force on a particle equals the change in the particle’s kinetic energy KE: \(\mathrm{W=ΔKE=\frac{1}{2}mv_f^2−\frac{1}{2}mv_i^2}\). The work-energy theorem can be derived from Newton’s second law. Work transfers energy from one place to another or one form to another.
In science, work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form, for a constant force aligned with the direction of motion, the work equals the product of the force strength and the distance traveled.
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 …
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.
When work done on an object increases only its kinetic energy, then the net work equals the change in the value of the quantity 12mv2 1 2 m v 2 . This is a statement of the work–energy theorem, which is expressed mathematically as. W = ΔKE = 1 2mv22 − 1 2mv21. W = Δ K E = 1 2 m v 2 2 − 1 2 m v 1 2.
The net work \ ( {W}_ {\text {net}}\) is the work done by the net force acting on an object. Work done on an object transfers energy to the object. The translational kinetic energy of an object of mass \ (m\) moving at speed \ (v\) is \ (\text {KE}=\frac {1} {2} {\text {mv}}^ {2}\).
