As an object moves from point A to point B only two forces act on it: one force is nonconservative and does -40 J of work, the other force is conservative and does +60 J of work. Between A and B, O A. the potential energy of object decreases, mechanical energy decreases O B. the potential energy of object increases, mechanical energy decreases O C. the potential energy of object increases, mechanical energy increases O D. the potential energy of object decreases, mechanical energy increases
