1. Energy Forms

2. What is Energy? Energy is the ability to do work
It allows us to change or move matter
We have learned to utilize energy to make life more comfortable and efficient
Energy occurs in many forms

3. Two Main Groups Energy can be divided into two main groups:
KINETIC: energy of motion
Motion of waves, molecules, substances, and objects
Radiant, Thermal, Mechanical, Sound, Solar
POTENTIAL: stored energy
Think of it as the “potential” for active energy
Examples include: Chemical, Electrical, Gravitational, Nuclear

4. Types of KINETIC Energy

5. Thermal Energy Thermal = Heat
As molecules in a substance move more quickly, they produce heat and thermal energy is increased
Geothermal Energy- heat energy from the inside the Earth
Geo = Earth

6. Examples of Thermal Energy

7. Radiant Energy Travels in waves
Includes light, x-rays, gamma rays, and radio waves
Also called electromagnetic
Solar energy is a special type of radiant energy that combines heat and light to warm the Earth
A special

8. Examples of Radiant Energy

9. Mechanical Energy Energy produced by moving parts or objects Machines
Your body
The faster the motion the greater the energy
Think of a car crash

10. Examples of Mechanical Energy

11. Types of POTENTIAL Energy

12. Chemical Energy Stored in the bonds of atoms and molecules
Energy released from chemical reactions
Is converted into other forms of energy when bonds are broken or combined
Biomass- is stored chemical energy that we get from living things
Bio = living things
Use coal to create fuel

13. Examples of Chemical Energy

14. Electrical Energy Energy created by the movement of charged electrons
Often travel through wires or circuits
Usually converted into other forms of energy

15. Examples of Electrical Energy

16. Nuclear Energy Energy stored in the “nucleus” of atoms
Two processes to access this energy:
NUCLEAR FISSION: splitting one large nucleus into two smaller ones
NUCLEAR FUSION: combining two smaller nuclei into one larger one

17. Examples of Nuclear Energy

18. Energy Transformations
Occur when one form of energy is “transformed” or converted into another more useful form
For example:
Electrical Energy Light and Thermal energy
