1. The total mechanical energy of a system: a. is split equally between kinetic energy and gravitational potential energy. b. is constant as long as only conservative forces act on it. c. is either only kinetic energy or only gravitational potential energy at any given time. d. cannot be determined for most naturally occurring systems. For this question, I think the answer is A. This is because Total Mechanical Energy is eqaul to Potential Energy + Kinetic Energy. Is my reasoning right?
