Work is defined as the product of the applied force and the parallel distance over which it acts, measured in joules. There are two main types of energy: kinetic energy, which is the energy of motion; and potential energy, which is stored energy. Energy can change forms but is never created or destroyed based on the law of conservation of energy. Power is the rate at which work is done and is measured in watts, with one watt equaling one joule per second. The document then concludes with homework assignments.
