A flywheel is a rotating mechanical device that is used to store rotational energy that can be called up instantaneously. At the most basic level, a flywheel contains a spinning mass in its center that is driven by a motor – and when energy is needed, the spinning force drives a device similar to a turbine to produce electricity, slowing the rate of rotation.

Aprende másMechanical Energy
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.
