According to Dr. Ray Batina of Washington State University, zero economic profit is the profit maximization point. At this point, price is equal to marginal cost. This scenario only applies to a perfectly competitive mar... More »

Elastic energy is the potential energy stored in a material or physical system as the volume or shape is distorted. When objects are stretched or compressed, elastic energy is stored, according to the Physics Classroom. More »

The principle of the conservation of mechanical energy states that mechanical energy is constant as long as it is in an isolated system and subject only to conservative forces. Mechanical energy itself is the energy that... More »

Objects that are not moving have potential energy, which is converted to kinetic energy to enable motion, according to LiveScience. Potential energy becomes kinetic energy when work is performed on an object, such as pus... More »
