Forms of Energy

S8P2 c.

QuestionAnswer
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? 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 kinetic 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
