WebThe 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 more general systems than the particle system mentioned here, work can change the potential energy of a mechanical device, the heat energy in a thermal system, or the electrical energy in an electrical device. WebPoynting's theorem states that the rate of energy transfer per unit volume from a region of space equals the rate of work done on the charge distribution in the region, plus the energy flux leaving that region. Mathematically: where: − ∂ u ∂ t {\displaystyle - {\frac {\partial u} {\partial t}}} is the rate of change of the energy density ...

(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. From the equation, v 2=u 2+2as, we get v 2–u 2=2as 21(v 2–u 2)=as
