memorize

• Power = Work done/Time taken
• work = force × distance moved
• W = F d =ΔE
• moment = force × perpendicular distance from pivot
• KE = 1/2 x mass x velocity^2
• GPE=mass×gravitational field strength×height
• force in a spring= spring constant × extension   
• Efficiency = useful energy input/total energy input x 100%
• Nuclear fusion is the process inside the sun that generates energy. It involves fusing small nuclei together to make larger nuclei.
• Nuclear fission happens inside nuclear power plants. This involves the splitting of a large nucleus into two smaller ones.
• Energy resources that do not rely on the sun: tidal power, nuclear power and geothermal power. 
• Transferable Energy

  thermal energy

  electric

  mechanical
• Nuclear fission is when 2 fast hydrogen nuclei collide and fuse to form a helium nucleus

  (requires high temp and pressure)
• Power is the work done per unit time
