What is work energy theorem? Prove it.
Answers
Answer:
Work energy theorem states that the change in kinetic energy of an object is equal to the net work done on it by the net force. Let us suppose that a body is initially at rest and a force. is applied on the body to displace it through. along the direction of the force.
Explanation:

The work-energy theorem also known as the principle of work and kinetic energy states that the total work done by the sum of all the forces acting on a particle is equal to the change in the kinetic energy of that particle.
Fd is the work done by the force F to move the object through a distance d. ... ΔK = change in KE of the object. From equation (ii), it is clear that the work done by a force on an object is equal to the change in kinetic energy of the object.
