State work energy theorem and prove it for various force

1.	State work energy theorem and prove it for various force
Answer» that kinetic energy of an OBJECT is GIVEN by K=1/2mv^2differentiating with respect to time t,we get,dk/dt=d/dt(1/2mv^2)dk/dt=1/2m2vdv/dtdk/dt=Mav [a=dv/dt]dk/dt=f×dx/dtdk=fdx.therefore,TOTAL work DONE -kf-ki=W
