Kinetic energy
Kinetic energy
Stored by an object that is moving
Magnetic energy
Magnetic energy
Stored by two magnets attracting or repelling each other
Thermal energy
Thermal energy
Stored in an object due to its heat
Chemical energy
Chemical energy
Stored in chemical bonds
Electrostatic energy
Electrostatic energy
Stored by two charges attracting or repelling
Elastic potential energy
Elastic potential energy
Stored in an object that has been stretched or compressed
Gravitational potential energy
Gravitational potential energy
Stored by an object when it is lifted to a height
Nuclear energy
Nuclear energy
Stored inside the nuclei of atoms
Conservation of energy
Conservation of energy
Energy cannot be created or destroyed, only transferred
Wasted energy
Wasted energy
Energy transferred into a form that is not the desired outcome
Specific heat capacity ()
Specific heat capacity ()
Energy to raise temp. of 1 kg of substance by 1°C
Renewable energy
Renewable energy
Sources of energy that never run out
Higher thermal conductivity effect
Higher thermal conductivity effect
Heat travels through material more easily
Lower thermal conductivity effect
Lower thermal conductivity effect
Less energy is lost as heat
Lubrication (reducing energy waste)
Lubrication (reducing energy waste)
Oil in motor reduces friction, less energy lost as heat
