ENERGY
TEST PREP
| Term | Definition |
|---|---|
| Chemical | Stored in bonds of atoms and molecules. |
| Radiant | Energy that comes to us in waves. Electromatic waves. |
| Thermal | The vibration and movement of molecules. |
| Mechanical | An objects movement creates energy. |
| Sound | Vibrations that are transmitted through air,water or another medium and produce a sensation in the air. |
| Nuclear | Stored in the nucleus of an atom when nucleus splits or combines. |
| Electrical | Electrons flow and produce energy. |
| Conduction | Transfers heat from a warm object to a colder one through direct contact. (Have to touch). EX. Burning logs in a fire place- New logs will burn when they are introduced to the ones that are already burning. |
| Convection | Transfers heat in a fluid through currents. EX. Convection ovens allow for heat to be spread quickly and easily for baking to happen faster. |
| Radiation | Heat is transferred through electromatic waves. EX. Radiation is how heat is transferred from the sun through space to earth. |
| Chemical Energy | Chemical Energy can come from fossil fuels (coal, petroleum, natural gas)* Chemical Energy can be transformed into heat energy and electricity. |
| Chemical Energy Definition | A form of potential energy that is stored in chemical bonds between atoms. |
| Electrical Energy | Energy caused by the movement of electrons. |
| Energy | Ability to do work. |
| Energy Transformation | A process in which energy changes from one form to another form while some of the other energy is lost to the environment. |
| Fission | The splitting of an atomic nucleus to release thermal energy. |
| Fusion | A process in which the nuclei of two atoms combine to form a larger nucleus. |
| Joule | A unit of work equal to one newton-meter, measurement of energy. |
| Kinetic Energy | The energy of motion. |
| Mechanical Energy | Kinetic or potential energy associated with the motion or position of an object. |
| Nuclear Energy | Energy stored in the nucleus of an atom, released when nucleus splits or combines. |
| Potential Energy | Stored energy. |
| Radiant Energy | Energy that travels in waves, electromagnetic waves. |
| Thermal Energy | Heat energy, the vibration and movement of molecules. |
| Coal | Black rock burned to make electricity. |
| Geothermal | Energy from heat inside the Earth. |
| Hydropower | Energy from flowing water. |
| Biomass | Energy from wood, waste, and garbage. |
| Wind | Energy from moving air. |
| Uranium | Energy from splitting atoms. |
| Propane | Portable fossil fuel gas often used in grill. |
| Petroleum (oil) | Fossil fuel for cars, trucks, and jets. |
| Natural Gas | Fossil fuel gas moved by pipeline. |
| Solar | Energy in rays from the sun. |
