Proof of work energy theorem

WebA physical theory, and also the postulates on which it is based can only be validated, that means that every experiment done shows that the theory holds and in this case energy conservation holds. A physical theory can be proven only to be false even by one datum, and then the theory changes. WebJan 9, 2024 · Work done by the force equals the change in kinetic energy of the center of mass. So W = Δ K c m = 1 2 m V c m 2 and here is their proof To derive the translational part, we start with the equation of motion for the center of mass F = M d 2 R d t 2 = M d V d t The work done when the center of mass is displaced by d R = V d t is

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.
