Define kinetic energy?? with derivation of the formula?? ​

Derivation of Kinetic Energy Formula by Calculus

Work done = Final K.E. - Initial K.E. W = change in kinetic energy. The work done by a force is a measure of the change in kinetic energy of the body which proves the work-energy principle. On putting u = 0 in eq (7), we get that: W = 1/ 2 m v^ 2 - 0.
