Mathematical Formulas |
|
|
Chemical Energy |
energy stored within the bonds between molecules. example: Natural Gas, Coal, or Gasoline |
|
|
Thermal Energy (heat energy) |
energy of moving molecules example: Fire |
|
|
Mechanical Energy |
energy stored in objects by tension. when the tension is release motion occurs example: a spring |
|
|
Radiant Energy (light energy) |
energy related to the movement of light example: the sun provides radiant energy to warm the earth |
|
|
Electrical Energy |
energy that comes from tiny charged particles called electrons example: lightning |
|
|
Nuclear Energy |
energy created when the nuclei of atoms are split or fused example: nuclear power plants |
|
|

Heat |
|
|
Temperature |
average kinetic energy of an object |
|
|
Heat |
thermal energy |
|
|
thermal energy |
total energy |
|
|
same number of particles...higher temperature = |
thermal |
|
|
same temperature...has more particles = |
has more thermal |
|
|
conduction |
transfers heat within a body or between two bodies that are touching. |
|
|
convection |
circular movement that transfer het within air and water |
|
|
radiation |
the transfer of energy by electromagnetic waves through air or space. |
|
|
heat moves one way |
from warmer to cooler until they equal out |
|
|
Thermal Expansion |
as the thermal energy of a substance increases its particles expand or separate |
|
|
Heat Engine |
runs by converting heat energy to work energy |
|
|
Reverse heat engine |
Example: Refridgerator |
