This study guide covers the Law of Conservation of Energy, including the mathematical representation ME = K + U with kinetic (K) and potential (U) energies. It discusses conservative and nonconservative forces and their impact on mechanical energy, along with applying conservation of energy to various scenarios. The guide provides exam tips and common mistakes to avoid. Finally, it includes practice multiple-choice and free-response questions focused on energy conservation and the work-energy theorem.
