√ Definition or Explanation
Energy is defined as the ability to do work
Energy of a moving object
Stored energy in an object, often due to its position
Energy of an object due to its movement and position
Energy of electrons moving in one direction in a wire
Energy of sound waves moving through a substance
like air or water
Electromagnetic radiation (like light waves,
microwaves, radio waves, x-rays, etc.) that move in
wave forms
Internal energy of a substance caused by its atoms
and molecules moving and vibrating within the
substance
Energy stored in an object from a push or a pull (like
pressing in a spring or stretching a rubber band)
The energy an object or substance has because of its
vertical position
Energy stored in the nucleus of an atom, released if
the atom is broken apart
Energy stored in the bonds between atoms, released if
the bonds are broken by a chemical reaction
The change of energy from one form to another
Energy can be transformed from one form to another,
but it cannot be created or destroyed
Movement of energy from one place to another
Movement of heat from one SOLID to another, from
warmer to colder
Transfer of heat from one place to another in LIQUIDS
or GASES, from warmer areas to colder areas
Heat transfer from fire or the sun in the form of wave
energy being emitted (sent out)
