1 DIFFERENT FORMS OF ENERGY

2

3 Two Basic Energy Types Potential Energy Kinetic Energy
Energy that is stored Energy of motion

4 Electromagnetic Energy
Energy that travels in waves (released into space by stars)

5 Visible Light Exists as both waves and particles
Travels at a constant speed of 186,000 mph (3.0x108 m/s) Solar energy from the sun is where most of the energy on earth comes from

6 Types of kinetic energy

7 Thermal Energy Energy of moving particles (micro) Heat
Created by light, sound, friction, nuclear radiation, fission, fusion

8 Mechanical Energy Energy of moving parts (macro) Normally uses gears
Moving wheels on a bike, blades on a fan, hands on a clock

9 Electrical Energy Energy of electrons moving through a wire
Direct Current (DC) electricity comes from batteries Alternating Current (AC) electricity is in the wall outlet Measured in volts—Flow is current (EMF—electromotive force)

10 Magnetic Energy Energy causing a push or pull
James Maxwell showed relationship between electricity & magnetism (remember electromagnetic energy) MRIs (magnetic resonance imaging)

11 Forms of Potential Energy

12 Chemical Energy Energy stored in chemical bonds
Food, fuel, batteries, all things flammable

13 Nuclear Energy Energy stored in the nucleus of atoms
2 Types: Fission (splitting) & Fusion (joining)

14 Energy stored in materials that are stretched
Elastic Energy Energy stored in materials that are stretched

15 Gravitational Energy Energy stored in objects due to their position above the earth’s surface Hydroelectric power is produced using gravitational energy

 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.
