I am solving work and energy objective from HC Verma.I got a question in which I have a basic doubt.The question is total work done on a particle is equal to change in kinetic energy always.But,I think it was wrong bcz if a body falls from a inclined plane and its final velocity is 'v' and it moves through height 'h' ,then total work done =mv2/2+mgh.But,in the question it is mention that total work done is only equal to change in kinetic energy.So,the work done must only be equal to mv2/2,butfrom thisway I can't get the answer.Please correct me where I was wrong.
