The basic equation to illustrate this is: The activity of work essentially involves the transfer of energy. Advertisement. Please tell us where you read or heard it (including the quote, if possible). Energy occurs in several forms-potential as in a compressed spring or a mass in a high position, kinetic as in motion, chemical as in petroleum and nuclear as in the binding forces of the atomic nucleus. This process also releases a tremendous amount of energy. 's' : ''}}.
