KS4 Conervation and dissipation of energy

In this section, which is divided into two sub-sections, we will learn more about energy transfers, in particular that not all energy transfers are useful. Some are wasted! This is where the idea of efficiency comes in.

Section 4.1.2 Conservation and dissipation of energy is divided into 2 sub-sections.These are:

The two sections are strongly related as you will find out.
