Review the units of work, energy, force, and distance. Use the equations for mechanical energy and work to show what is work and what is not. Make it clear why holding something off the ground or carrying something over a level surface is not work in the scientific sense.
type. The amount of energy transformed (∆E) is called work W. The body losing energy does work, the body gaining energy has work done on it. Work is given by the force multiplied by the displacement through which the force acts, or: where F = force (N), d = displacement (m) KE = ½ mv2 Work = Change in Energy = Force × displacement

Represent the work done by any force. Evaluate the work done for various forces. In physics, work represents a type of energy. Work is done when a force acts on something that undergoes a displacement from one position to another.
Topic: The Basics of Work, Energy, and Power. Objectives: To describe the conditions under which positive and negative work are done and to use the work equation to calculate the amount of work done.
