Question

state and prove work energy theorem​

Answer 1

the change of kinetic energy is equal to the net working energy

Answer 2

It states that work done by force acting on a body is equal to the change produced in its kinetic energy.  If vector F force is applied to move an object through a distance dS  Hence W = Kf – Ki Where Kf and Ki are final and initial kinetic energyRead more on Sarthaks.com - https://www.sarthaks.com/127534/state-and-prove-work-energy-theorem-analytically
