1. Energy

2. Energy
Energy comes in different forms: mechanical (kinetic and potential), electrical, chemical, radiant (solar), and thermal.

3. All matter is made of tiny particles called atoms
All matter contains energy
The total energy of matter depends on the type, state, amount, and motion of the matter
Potential energy is the stored energy of matter
Kinetic energy is active energy

4. Thermal
Thermal energy is the energy that is associated with the motion of the particles in a substance.
All matter is made up of atoms (particles) that move faster when they heat up. The faster the particles move, the higher the temperature.
Heat energy is the transfer of thermal energy.
Heat energy always moves from hotter objects to cooler objects.

5. Radiant
Energy which is transferred through electromagnetic waves such as visible light, ultraviolet light or Xrays.
Solar energy is a type of radiant energy.
Green plants use solar energy during photosynthesis.
Most of the energy that we use on Earth originally came from the Sun.
Sources of radiant energy include, but are not limited to, stars, light bulbs, and microwaves.

6. Chemical
Chemical energy is energy stored within the chemical bonds in matter.
Chemical energy can be released, for example in batteries or sugar/food, when these substances react to form new substances. Electrical energy
Electrical energy is the energy flowing in an electric circuit.
Sources of electrical energy include: stored chemical energy in batteries; solar energy in solar cells; fuels or hydroelectric energy in generators.

7. Mechanical
Mechanical energy is the energy due to the motion (kinetic) and position (potential) of an object.
When objects are set in motion or are in a position where they can be set in motion, they have mechanical energy.

8. Mechanical Potential Potential energy is stored energy.
Mechanical potential energy is related to the position of an object.
A stretched rubber band has potential energy. This is called elastic potential energy.
A book on a shelf has potential energy. Since gravity can pull the book to the floor, this is called gravitational potential energy. The height and mass of an object affect gravitation potential energy.

9. Gravitational Potential Energy
Gravitational potential energy is greater when the height of an object is greater because more kinetic energy was required to raise the object to the greater height.
