Webb16 juli 2024 · The net work on a system equals the change in the quantity 1 2mv2. Wnet = 1 2mv2 − 1 2mv2 0. The quantity 1 2mv2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) WebbNet work is defined to be the sum of work on an object. The net work can be written in terms of the net force on an object. Fnet. In equation form, this is Wnet = Fnetdcosθ where θ is the angle between the force vector and the displacement vector.
