Physics (Conservation and dissipation of energy
Energy stores and transfer
Thermal
Kinetic
Gravitational Potential
Elastic Potential
Chemical
Nuclear
Sound
Megnetic
Energy cannot be created or destroyed and so for a store to increase energy must be transferred.
Energy and work done
Work done means energy transferred
Energy = Force x dist
Gravitational potential
Is the amount of energy object has when above the ground
GPE = Mass x Gravity strength x Height
Kinetic energy
Energy when something is moving
Energy = Mass x 0.5 x (v x v)
Elastic potencial
Energy = newtons x 0.5 x Extension squared
Energy when an object compressed or extended
Energy dissipation and efficiency
Wasted energy = Total - useful
Efficiency = Useful ÷ Total
Energy and power
Power = Energy ÷ Time
