Magnetic
Energy stored when repelling or attracting poles are manipulated.
Internal (thermal)
Total energy of particles in an object, including kinetic energy.
Chemical
Energy stored in chemical bonds between molecules.
Kinetic
Energy of a moving object.
Electrostatic
Energy stored in repelling or attracting charges.
Elastic potential
Energy stored when an object is stretched or squashed.
Gravitational potential
Energy of an object at height.
Nuclear
Energy stored in the nucleus of an atom.
Pathways for transferring energy
Mechanical work, electrical work, heating, radiation.
Systems and stores
Energy transfers between different stores over time.
Transfer diagrams
Show energy stores and transfers with boxes and arrows.
Sankey diagrams
Display energy transfers in a system with arrows splitting into different points.
Conservation of energy
Energy can be transferred, stored, or dissipated but not created or destroyed.
Examples of conservation of energy
Skydiver and smartphone energy transformations.
Gravitational potential energy formula
ΔGPE = mass x gravitational field strength x change in vertical height.
