Conservation and dissipation of energy

Loading...

Description

The problem with energy is that there’s only so much of the stuff to go round.  In this important video, we’ll look at the meaning of the Principle of Conservation of Energy, before going on describe the various ways in which useful energy can be dissipated from a system and the steps which can be taken to minimise such ‘wasted’ energy.  The video finishes with a few examples on the use of both forms of the equation for the efficiency of an energy transfer.

Key Words
