OBJECTIVES
1. Identify situations in which conservation of mechanical energy is valid.
2. Recognize the forms that conserved energy can take.
3. Solve problems using conservation of mechanical energy.
PS5a: The total energy of the universe is constant. Energy can be transferred by collisions
in chemical and nuclear reactions, by light waves and other radiations, and in many other
ways. However, it can never be destroyed. As these transfers occur, the matter involved
becomes steadily less ordered.
PS5b: All energy can be considered to be either kinetic energy, which is the energy of
motion; potential energy, which depends on relative position; or energy contained by a
field, such as electromagnetic waves.
