Non-conservative forces If we look at a block-spring system, oscillating on a rough surface, we will see that the amplitude of the motion decreases continuously. Because of the frictional force, the mechanical energy is no longer conserved. If we look at a system on which several conservative forces act, in addition to the friction force. The total work done on the system is

Unformatted text preview: which is equal to the change in the kinetic energy of the system (work-energy theorem). Each conservative force can be identified with a potential energy and We can now rewrite the expression for the change in the kinetic energy of the system The work done by the friction force is equal to the change in the mechanical energy of the system....
