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 define the term system

• I can recall that energy cannot be created or destroyed

• I can use describe how kinetic energy changes over time

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

• I can rearrange Ek = ½ mv2• I can use Ek = ½ mv2

• I can use describe how elastic potential energy changes

• I can rearrange Ee = ½ ke2

• I can use Ee = ½ ke2

• I can use describe how gravitational potential energy changes

• I can recall the units needed for Ep = mgh

• I can rearrange Ep = mgh

• I can use Ep = mgh

• I can recall the units needed for ΔE = mcΔθ

• I can rearrange ΔE = mcΔθ

• I can use ΔE = mcΔθ

• I can use define power

• 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 P = W /T

• I can rearrange P = W/T

• I can use P = W/T

• I can recall that energy cannot be created or destroyed

• I can describe what happen to wasted energy

• I can recall ways to reduce wasted energy

• I can describe how insulation can reduce energy loss

• I can describe why a system might not be 100% efficient

• I can describe whys to increase the efficiency of a system

• 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

• I can state the different sources that can be used to get energy

• I can determine if a resource is renewable or finite

• I can consider the impact that using these resources has on the environment

• I can discuss the advantages and disadvantages of each source of energy
