Name:____________________________________________________________ Date:_________________________ Period:_____________ Notes and Handouts Types of Energy Chart Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven or keeps ice frozen in the freezer. It plays our favorite songs on the radio and lights our homes. Scientists define energy as the ability to do work. Energy is found in different forms such as light, heat, sound, and chemical. There are many forms of energy, but they all can be put into two categories either kinetic or potential. When you finish filling in the energy chart below, return to the kinetic or potential and try to list each type of energy as either kinetic or potential. KINETIC (moving) POTENTIAL (stored) HEAT (THERMAL) Define this type of energy (in your own words) What is the source or what produces this type of energy? Give several examples of how this type of energy is used in today’s world. CHEMICAL SOUND ELECTRO-MAGNETIC Define this type of energy (in your own words) What is the source or what produces this type of energy? Give several examples of how this type of energy is used in today’s world. NUCLEAR MECHANICAL LIGHT (RADIANT) Types of Energy: Answer Key KINETIC (moving) Electrical, Light, Heat, Sound HEAT (THERMAL) POTENTIAL (stored) Chemical, Mechanical, Nuclear CHEMICAL Define this type of energy (in your own words) Heat energy is created in the movement of atoms. Boiling water, burning wood, and rubbing your hands together really fast are all examples of heat energy. Geothermal, and passive solar are sources of heat energy, but biomass (a type of chemical energy) can be burned to produce heat energy. Chemical energy is stored in the bonds of molecules. This is a form of potential energy until the bonds are broken. Products that contain chemical energy include: TNT, baking soda, and a match. What is the source or what produces this type of energy? Friction The bonds between two substances. Or the mixing of two different substances. Give several examples of how this type of energy is used in today’s world. Heating a house, cooking Coal, fossil fuels, Food SOUND Sound energy is the movement molecules in the air that produces vibrations. It's this bumping or mechanical energy that moves across the room, not the air molecules! The bumping produces sounds energy. The bumping of molecules Music, speaking ELECTRO-MAGNETIC ENERGY Define this type of energy (in your own words) What is the source or what produces this type of energy? Give several examples of how this type of energy is used in today’s world. Magnetic energy is the attraction of objects made of iron. Medical equipment (MRI scanning), compass, refrigerator magnets are all examples of magnetic energy. Any type of energy source that uses a generator in the process to make electricity uses magnetic energy. NUCLEAR ENERGY Nuclear energy is the energy stored within atoms. Nuclear energy is unusual in that it can give off energy in the form of light or heat, but it is the change in the atom's makeup that produces the energy. Submarines, power plants, and smoke detectors all use nuclear energy. Nuclear power plants use uranium, a radioactive element, to create electricity. MECHANICAL Mechanical energy is the movement of machine parts. Wind-up toys, grandfather clocks, and pogo sticks are examples of mechanical energy. Wind power uses mechanical energy to help create electricity. LIGHT (RADIANT) ENERGY Light energy is the movement of photons. (The light specturm of electromagnetic waves shows light energy.) All life on earth is dependent on light energy from the sun. Examples of light energy include radio waves (AM, FM, TV), microwaves, X-rays, and plant growth. Active solar energy uses photovoltaic panels and light to turn light energy into chemical energy.
