Students will explain that work is a transfer of energy and that conservation of energy in an isolated system is a fundamental physical concept.

Define mechanical energy as the sum of kinetic and potential energy Determine, quantitatively, the relationships among the kinetic, gravitational potential and total mechanical energies of a mass at any point between maximum potential energy and maximum kinetic energy. Analyze, quantitatively, kinematics and dynamics problems that relate to the conservation of mechanical energy in an isolated system Recall work as a measure of the mechanical energy transferred and power as the rate of doing work Describe power qualitatively and quantitatively Describe, qualitatively, the change in mechanical energy in a system that is not isolated.
