Presentation transcript:

Kinetic and Potential Energy have many forms

1. Mechanical Energy - Energy associated with motion or position

Examples: most moving objects have mechanical energy

2. Thermal Energy (Heat) - Total energy of the particles in an object

Example: Heating causes the particles to move faster = more thermal energy

3. Chemical energy - Energy stored in chemical bonds

Examples: wood, food, gasoline, batteries

4. Electrical energy - Energy of moving electrons

Example : electric outlet

5. Radiant or Electromagnetic (Light) energy Travels in waves

Examples: lightbulb, microwave

6. Sound energy- Caused by an object’s vibrations

Example : guitar, boombox

7. Nuclear energy - Potential energy stored in the nucleus of an atom

Example : nuclear power plants, sun

Energy Conversions - A change from one form of energy to another

Conversion example 1 Lamp : electrical energy converts to light energy

Conversion example 2: Water heater : Chemical energy of gas to thermal (heat ) energy

Conversion example 3: Human body : converts chemical energy in food to mechanical energy
