Question

The total mechanical energy of a system is conserved if the


a. forces, doing work on it, are not conservative

b. forces, doing work on it, are damped

c. forces, doing work on it, are conservative

d. forces, doing work on it, are viscous​

Answer 1

Answer:

If only internal forces are doing work (no work done by external forces), then there is no change in thetotal amount ofmechanical energy. The total mechanical energy is said to beconserved.
