Energy The ability to do work or cause changes in matter
Kinetic Energy Moving bucket Energy of Motion
Gravity Potential Energy Stored Energy or Energy of Position
Forms of Energy Remember “MRS. CHEN”
Mechanical Radiant Energy carried by electromagnetic radiation (light) from a source Energy of matter caused by its position or its motion
Chemical Sound Energy stored in matter because of its chemical makeup Energy from the vibration of an object (that produces a noise) Sound
Electrical Thermal (Heat) Energy that is related to heat and temperature of matter Thermal (Heat) Energy due to charged matter/moving electrons
Energy stored in the nucleus of an atom Nuclear Energy stored in the nucleus of an atom
Law of Conservation of Energy Energy is neither created nor destroyed; it is changed (converted) from one form into another.
Sources of Energy U 2 35
Renewable Energy Source Energy source that can be replaced by natural processes in a short amount of time Biomass Hydropower
Nonrenewable Energy Source Energy source that is used much faster than it can be replaced by natural processes U 2 35 Coal Propane Oil Uranium Natural Gas
Inexhaustible Energy Source Energy source that cannot be used up in Earth’s “lifetime” Wind Geothermal Solar
Coal Solid fossil fuel formed from the buried remains of plants and animals that lived millions of years ago
NATURAL GAS AND OIL IN POCKETS OF ROCKS ROCK HOLDS IN NATURAL GAS Fossil Fuel ROCK NATURAL GAS AND OIL IN POCKETS OF ROCKS Dirt ROCK HOLDS IN NATURAL GAS Coal Oil Natural Gas formed from the buried remains of plants and animals that lived millions of years ago
Petroleum Liquid fossil fuel formed from the buried remains of plants and animals that lived millions of years ago
ROCK HOLDS IN NATURAL GAS NATURAL GAS AND OIL IN POCKETS OF ROCKS Dirt Natural Gas ROCK HOLDS IN NATURAL GAS Gaseous fossil fuel formed from the buried remains of plants and animals that lived millions of years ago
A portable gas that comes from the fossil fuels oil and natural gas. Propane A portable gas that comes from the fossil fuels oil and natural gas.
Comes from the mineral Uranium that is buried in the ground Nuclear Energy Comes from the mineral Uranium that is buried in the ground Fission
Energy from moving water Hydropower Energy from moving water
Biomass Energy from the burning of once-living things (wood, plants and garbage)
Solar Energy Energy from the sun
Wind Energy from moving air
Energy from heat inside the earth Geothermal Energy Energy from heat inside the earth

Methods of Energy Transfer Convection Conduction Radiation
Transfer of energy through matter from particle to particle Conduction Transfer of energy through matter from particle to particle
The transfer of heat energy in a gas or liquid by movement of currents Convection The transfer of heat energy in a gas or liquid by movement of currents Ocean Currents are an example of Convection.
Radiation Electromagnetic waves that directly transport ENERGY through space. Example: Sunlight
Energy Transformation The process of energy changing from one form to another Example: electrical energy to radiant energy
Benjamin Franklin Discovered that lightning is a stream of electrified air, known as plasma. Helped to develop many of the energy terms we use today. Example: conductor, battery
