Energy Flashcards
electrical energy
electrical energy is the energy made available by the flow of electric charge through a conductor.
Law of conservation of energy
The Law of conservation of energy is the law that energy cannot be destroyed or created.
Gravitational Potential energy
Gravitational Potential energy is energy stored due to the height of an object above a base level
Chemical energy
chemical energy is potential energy derived from chemical reactions
Elastic Potential energy
elastic potential energy is the potential energy stored in a stretched elastic material
Nuclear energy
nuclear energy is the energy stored at the center of atoms, the tiny particles that make up all substances. Nuclear energy can be released from the radioactive metals uranium or plutonium, and transformed into electrical energy in a nuclear power station.
Efficiency
Efficiency is the fraction of energy supplied to a device as useful energy. It is usually expressed as a percentage.
Luminous
Luminous is when something is releasing its own light
Incandescent
Incandescent describes objects that emit light when they are hot
Bioluminescent
Bioluminescent describes living things that release light energy
Non-Luminous
Non-Luminous describes objects that do not emit their own light, but can be seen by reflected light
Scattered
Scattered describes light sent in many directions by small particles within a substance
Visible Spectrum
Visible Spectrum is the different colors that combine to make up white light; they are separated in rainbows
Dispersion
Dispersion is the separation of the colors that make up white light. Each color is bent differently when it enters or leaves a glass prism.
Electromagnetic Radiation
Electromagnetic Radiation is radiant energy such as radio waves, infrared, visible light, X-rays and gamma rays released by magnetic or electric fields
