Forms of Energy Potential or Kinetic

All forms of energy fall under two categories Potential: Stored energy Energy of position Chemical Nuclear Stored mechanical Gravitational Kinetic Energy of motion Waves,electrons,atoms, molecules, and substances Radiant Thermal Motion Sound Electrical

Matter All matter is made up of particles in motion. Because the particles are in motion, they have kinetic energy. At higher temperatures particles move faster and therefore have more kinetic energy. Ice----  Water---  Steam

Thermal Energy Thermal Energy (or heat) is the internal energy in substances-the vibration and movement of atoms and molecules within the substance. Geothermal energy is an example of thermal energy.

Heat is energy created by the vibration and movement of molecules.

Chemical Energy Chemical Energy is the energy of a compound that changes as the atoms are rearranged. Chemical energy is a form of stored or potential energy. The more atoms that are bonded together in a compound, the more potential energy that compound has. Wood has stored chemical energy  burns  heat We eat  grow.

Chemical energy is the energy stored in the bonds of atoms and molecules. Biomass, petroleum, natural gas, propane, and coal are examples of stored chemical energy.

It takes energy to grow--- Chemical Energy stored in simple sugars. The energy to make these sugars comes from light energy. Most of this light energy comes from the sun. Plants absorb the light energy and store it in their leaves, stems, fruits, and roots as chemical energy. They use the energy to grow! When we eat plants, or animals that eat plants, we absorb the chemical energy so we can grow!

Electrical Energy Electrical energy is the movement of electrons. Lightning & electricity are examples of electrical energy.

Because electricity is created by the changing positions of magnets, electricity can be considered a form of potential energy. Electrical Energy

When a device is plugged into an outlet and turned on, electrons move back and forth within the wires of the cord, so electrical energy is also considered Kinetic energy too.

Sound Energy

Sound is the movement of energy through substances (solid, liquids, & gases) in longitudinal (compression/rarefaction) waves.

Sound Energy  Is both potential and kinetic.  To make an object vibrate, work must be done.  You change the position therefore you create potential energy.  When released, the movement (vibration) is passed to air particles=kinetic energy.

Radiant Energy (Light)

Radiant Energy Radiant energy is electromagnetic energy that travels in transverse waves. Radiant energy includes visible light, x- rays, gamma rays, and radio waves. Solar energy is an example of radiant (Light) energy.

The Electromagnetic Spectrum Transverse Wave:

Nuclear energy Nuclear energy is energy in the nucleus (core) of an atom. Atoms are tiny particles that make up every object in the universe. There is enormous energy in the bonds that hold atoms together.

Nuclear energy Nuclear energy can be used to make electricity. First, the energy must be released! It can be released in two ways: Nuclear fusion and nuclear fission.

Nuclear fusion In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. This is how the sun produces energy.

Nuclear fission During nuclear fission, a small particle called a neutron hit the uranium atom and it splits, releasing a great amount of energy as heat and radiation. This caused more neutrons to be released to go on and bombard other uranium atoms, and the process repeats itself over and over. This is called a chain reaction.
