Energy Vocab

Energy vocabulary words with definitions

Work the transfer of energy through motion
Atomic Weight the total number of protons and neutrons in the nucleus
Atomic Weight = Number of Protons + Number of Neutrons
Atomic Symbol the abbreviation of the atom name
Proton Positive charged, found in the nucleus
Neutron Neutral mass in the nucleus
Electron Negative charged mass spinning around the nucleus
Sub-atomic particles: Proton, Neutron, Electron
Atomic Number = Number of Protons and number of Electrons
Atomic Number the number of Protons and Electrons in an atom
The chemical formula states the types of atoms (i.e. elements) in the compound, the ratio of the different atoms in the compound
Compound is a substance which is made up of two or more different elements chemically combined together.
Compound pure substances that are the unions of two or more different elements. They can be broken into simpler substances by chemical means.
Molecule is made up of two or more atoms chemically combined
Elements simplest form of pure substance. They cannot be broken into anything else by physical or chemical means. An element is a substance made up of only one type of atom
Mixtures two or more substances that are not chemically combined with each other and can be separated by physical means
Hydroelectric energy Energy for the flow of water
Biomass energy Energy from burning organic or living matter
Wind energy Energy from the wind
Law of Conservation of Energy Energy can neither be created nor destroyed. Energy is always changing (transforming) from one kind to another. The total energy of an object never changes.
Potential Energy exists whenever an object which has mass, has a position within a force field.
Kinetic Energy exists whenever an object which has mass is in motion with some velocity
Mechanical energy is the movement of machine parts
Sound energy is the movement molecules in the air that produces vibrations
Thermal energy is the internal energy in substances-the vibration and movement of atoms and molecules within substance.
Nuclear energy is the energy stored in the nucleus of an atom
Electrical energy is the movement of electrons
Chemical energy is the energy stored in the bonds of atoms and molecules
Radiant energy is the movement of photons
Nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption
Renewable resources are natural resources that can be replenished in a short period of time
Geothermal energy Energy from Earth’s heat
Solar energy energy from the sun
