Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.


 • I can recall the different types of energy and give examples  Video 1  Video 2 

 • I can describe the energy changes involved in a range of common situations

 • I can recall that energy cannot be created or destroyed

 • I can draw and use Sankey diagrams to represent energy transfers

 • I can define the term system

 • I can recall the units needed for E = Fd

 • I can rearrange E = Fd

 • I can use E = Fd

 • I can recall the units needed for GPE = mgh

 • I can rearrange GPE = mgh

 • I can use GPE = mgh

 • I can use describe how kinetic energy changes over time

 • I can recall the units needed for KE = ½ mv²

 • I can rearrange KE = ½ mv²

 • I can use KE = ½ mv²

 • I can convert between joules and newton-meters

 • I can state that most process have heat as wasted energy

 • I can describe what happens to wasted energy

 • I can recall the units needed for P = E / T

 • I can rearrange P = E/T

 • I can use P = E/T

 • I can recall the units needed for Efficiency = useful energy out/total energy in

 • I can rearrange Efficiency = useful energy out / total energy in

 • I can use Efficiency = useful energy out / total energy in

 • I can recall the units needed for Efficiency = useful power out / total power in

 • I can rearrange Efficiency = useful power out / total power in

 • I can use Efficiency = useful power out / total power in
