Nuclear fusion - A reaction in which nuclei combine to form more massive nuclei with the simultaneous release of energy., nuclear fission - A reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy., attractive force - The force by which one object attracts another., current - The rate at which “charge” flows past a point on a circuit. , electric charge - positive or negative charge generated from unequal number of protons and electrons; charge is generated from the flow of electrons through a material, electromagnetic force - attractive or repulsive force between electric charges and magnets, magnetic field - a region of space that surrounds a magnet and exerts a force on other magnets and magnetic objects; affects objects without touching them, parallel circuit - an electric circuit in which the devices are arranged on separate branches and charges have multiple paths to travel through, repulsive force - The force by which bodies repel one another., resistor - A device used to control current in an electric circuit by providing resistance., series circuit - An electric circuit connected so that current passes through each circuit element in turn without branching., switch - A device used to break or open an electric circuit or to divert current from one conductor to another., voltage - A measure of the difference in electric potential between two points in space, a material, or an electrical circuit, expressed in volts, fossil fuels - formed from the remains of ancient plants and animals that have been buried and altered over millions of years; known as crude oil, geothermal energy - thermal energy that is contained in and around magma; Can be harnessed by geothermal power plants, hydropower - Electricity produced from the kinetic energy of moving water., nuclear energy - Energy provided by nuclear fission., solar energy - Energy provided by the sun via thermal radiation, wind energy - kinetic energy of moving air that is converted into electrical energy by a windmill, electric circuit - a closed system and path that electric current can flow through, biomass - organic matter used as a fuel to burn in power stations to generate electricity, renewable energy sources - energy source replaced by natural processes faster than humans can consume the resource, nonrenewable energy sources - resources that cannot be replaced by natural processes as quickly as they are used,
