Electromagnetic- a magnet created by an electrical current.
Friction- a force of resistance on the surface of an object.
Kinetic- energy due to the motion of an object
Potential- energy that is stored in an object as a result of its position.
Heat- a form of thermal energy. Transfers energy from warmer object to cooler objects.
Insulator- a material in which heat and electricity cannot flow though.
Convection- the transfer of heat from one place to another though fluids
Conduction- transfer of heat within an object or between two objects that are touching. It is a point-by-point process of heat transfer.
Conductor- an object that allows the flow of electrical charge.
Radiation- energy that travels through space.
Temperature- the measure of heat. It's also a measure of how fast the atoms and molecules of a substance are moving. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.
Thermal energy- Energy that comes from heat.
Mechanical energy- the energy of motion that does the work. An example of mechanical energy is the wind as it turns a windmill.
Thermometer- a tool used to measure the temperature of an object.
Magnet- A piece of metal that attraction iron or steel. Magnets have two ends or poles, a north pole and a south pole. Opposite poles attract.
Fossil Fuels- Coal, oil, or natural gas, formed from the remains of prehistoric plants and animals.
Nonrenewable resources- Sources of energy that cannot be replaced in our lifetime.
Renewable resources- Sources of energy that can never be used up, such as wind, waves, and the sun.
