–40 J of work, the other force is conservative and does +60 J of work. Between A and B,

Select one:

the potential energy of object increases, mechanical energy decreases.

the potential energy of object decreases, mechanical energy increases.

the potential energy of object increases, mechanical energy increases

the potential energy of object decreases, mechanical energy decreases.
