Forms of Energy
S8P2 c.
| Question | Answer |
|---|---|
| Water that flows from behind a large dam can cause machines to produce electricity. What changes takes place? | Gravitational to mechanical energy to electrical energy. |
| Light is an example of which type of energy? | Electromagnetic which is often called radiant |
| When a hair dryer is being used, one of the energy transformations that takes place is | electrical to mechanical and thermal. |
| light | Another word for radiant; the only form of energy that we can directly see |
| nuclear energy | Energy released when atoms split or join together |
| kinetic energy | Energy of an object due to its motion |
| mechanical energy | Potential energy + Kinetic energy of an object |
| solar energy | Radiant energy that comes from the sun |
| geothermal energy | Use of heat from the Earth to transform energy |
| transformation | Change of energy that is constantly occurring |
| thermal energy | Heat energy; Increases when atoms move faster because of more energy. |
| tidal energy | Uses the gravitational pull of the Earth and moon to transform energy |
| Law of Conservation of Energy | Energy is neither created nor destroyed. It is only transformed into another type of energy. |
| wave energy | Uses the kinetic force of waves to transform energy |
| heat | Energy transferred at the atomic level due to a difference in temperature; another word for thermal |
| potential energy | Energy of an object due to its position |
| hydroelectric power | Renewable energy source that transforms the gravitational energy of water to mechanical energy of falling water into electricity |
| chemical energy | Energy stored in the bonds of chemical compounds that is released during reactions |
| electromagnetic energy | Energy made from vibrations of magnetism and electricity; only type of wave that can travel through empty space |
| magnetic energy | The energy within a magnetic field. |
| biomass | Natural materials and waste products that are burned to generate electricity |
| electrical energy | Energy that comes from the flow of an electric current through a conductor |
| sound energy | Caused by an object’s vibrations being transmitted through the air in the form of waves |
| energy | The ability to make matter move or change |
| radiant energy | Energy carried by light and other types of electromagnetic radiation |
| electricity | Flow of electrons. |
| wind energy | Wind turbines convert the mechanical energy in the wind into mechanical power. A generator can convert mechanical power into electricity. |
| fossil fuel | Fuel formed within the earth from decayed plants and animals; coal, oil, and natural gas - that got their energy from the sun. |
