The utilization of the potential energy stored in the pressurization of a compressible fluid is at the heart of the compressed-air energy storage (CAES) systems. The mode of operation for installations employing this principle is quite simple. Whenever energy demand is low, a fluid is compressed into a voluminous impermeable cavity, …

Mechanical Energy consists of two types of energy - the kinetic energy (energy of motion) and the potential energy (stored energy of position). The total mechanical energy is the sum of these two forms of energy. In a previous part of Lesson 1, it was said that work is done upon an object whenever a force acts upon it to cause it to be displaced.
