Mechanical Energy:
 Energy due to the position (potential) and motion (kinetic)
of an object
 Occurs when work is done on an object!
 Potential Energy + Kinetic Energy = Mechanical Energy
Thermal (Heat) Energy:
 Energy due to the motion or vibration of the molecules in an object
 More heat = MORE kinetic energy
 Less heat = LESS kinetic energy
 Temperature is a measure of kinetic energy
Chemical Energy:
 The energy that is stored in chemical bonds
 When chemical bonds are broken, energy
is released!
Electrical Energy:
 The energy of moving electrons  electricity!
 Anything that is powered by electricity
requires electrical energy!
Sound Energy:
 An object’s vibrations transmit sound energy
through the air
Light (Radiant) Energy:
 Produced by electromagnetic
waves of light that travel
Nuclear Energy:
 Energy that comes from changes in the nucleus of an atom
 The sun’s energy comes from nuclear fusion!
 Humans use nuclear fission to
generate energy!
