Kinetic and potential energies are the two types of mechanical energy.Energy is defined as the ability to do work In science, work and mechanical energy have different units. Work is defined as the product of the force and the distance moved by the force in the direction of the force. The potential energy of a body depends of its velocity. A body can never have both kinetic and potential energies A foot-pound (ft.lb) is also a unit of work. The total mechanical energy of a pendulum bob swinging freely without friction changes with time. Temperature is a physical quantity that scientists use to measure the degree of coldness or hotness of a body on a given scale. On the Fahrenheit scale, the boiling point of water is 100 oF. On the Celsius scale, 32 oC is the freezing point of water or the melting point of ice. On the Absolute scale, 273 K is equivalent to 0o C. When a body is supplied with heat, its temperature always goes up.
