Magnetic
When a system changes
Energy is transferred
Energy is transferred by
Heating radiation
Anything moving has a
Kinetic energy store
Energy lost in gpe store=
Energy gain I kinetic store
Specific heat capacity
How hard it is to heat something
Energy principle
Energy can be transferred or stored can’t be made or destroyed
Power is the rate of
Energy transferred
Conduction occurs in
Solids
Conduction is the process of
Vibrating particles transfer energy to neighbouring particles
Convection occurs in
Liquids gasses
Convection is the process of
Particles moving away from hotter to cooler regions
insulation reduces the rate of
Energy transfer by heating
Non renewable energy resources will
Run out one day
Example of non renewable
Coal oil gas
Renewable energy resources will
Never run out
Eg of renewable energy resource
Sun wind water waves hydro electricity geothermal tides bio fuel
Energy resources are used for t
Transport and heating
Not renewable energy resource eg for transport
Petrol diesel powers vehicle s
Renewable source for transport
Vehicles that run on bio fuels
Kinetic energy
Energy stored in a moving object
Gravitational potential energy
Energy stored in a object due to the position above the ground
Elastic potential energy
Energy stored in a stretched Spring
Thermal energy
Energy stored due to objects temp
