energy
the ability to do work
Electromagnetic Energy
energy of light and other forms that can travel through space
Thermal Energy
heat energy
Conduction
when heat is moved from one place to another through a solid, metals are good conductors of energy
Convection
when energy is moved through a liquid or gas by density differences
Radiation
The transfer of electromagnetic energy through space
Kinetic Energy
energy in motion; greatest when the mass or velocity is greater
Potential Energy
energy that is stored to be used as kinetic energy later; increases with weight and height.
Temperature
The measure of how much moving energy there is in the particles of a substance
Melting
A phase changes that occurs when a solid gains thermal energy and turns into a liquid.
Solidification/Freezing
A phase change that occurs when a liquid loses energy and turns into a solid.
Evaporation/Vaporization
A phase change that occurs when a liquid gains thermal energy and turns into a gas.
Condensation
A phase change that occurs when gas loses thermal energy and turns into a liquid.
Hydroelectric energy
renewable energy associated with the movement of water.
Chemical Energy
the potential energy stored in molecules such as food.
Mechanical Energy
energy associated with the motion or position of an object.
Electrical Energy
energy associated with moving electric charges.
Solar Energy
renewable energy from the sun.
Sound Energy
energy associated with the vibration of matter.
Law of Conservation of Energy
Energy cannot be created or destroyed, instead it is transferred or transformed into another form.
