# Work done by the conservative force on a system is equal to

a) the change in Kinetic energy of the system b) the change is potential energy of system c) the change in total mechanical energy of the system d) none of these
Can you answer this question?

Change in potential energy = - Change in work done
So the work done by the conservative force on a system is equal to the change in potential energy of the system
Hence b is the correct answer.
