WebThe work energy theorem states that work done on a body is equal to the net change in its energy. (P.E or K.E) Proof: Consider a body of mass ‘m’ moving with an initial velocity u. Let a constant force F acting on a body changes its velocity to v. Let s be the distance traveled.

WebBy applying the work-energy theorem, we have: ΔK = F (x) Δx. Since the force is conservative, the change in potential Energy can be defined as ΔV = – F (x) Δx. Hence, ΔK + ΔV = 0 or Δ (K + V) = 0 Therefore for every displacement of Δx, the difference between the sums of an object’s kinetic and potential energy is zero.
