This study guide covers Hooke's Law and springs, including the spring constant and elastic potential energy. It also explains conservative forces and their properties, contrasting them with dissipative forces. The guide explores gravitational potential energy in both uniform and non-uniform fields. Finally, it provides practice questions and exam tips covering energy conservation, graphical analysis, and derivations related to these concepts.
