Review

• Potential energy is what?

• Kinetic energy is what?

Potential or Kinetic? (Don’t write – answer outloud)

Energy Types Pg. 17

• What are some of the major types of energy?

Energy Types Pg. 17

1. Mechanical energy-

2. Radiant energy-

3. Electrical energy-

4. Light energy-

• the energy that makes things move.

• a combination of heat and light energy.

• energy made by the flow of tiny particles called electrons.

• a type of electromagnetic energy that is(isn’t) visible to humans.

5. Chemical energy-

6. Nuclear energy-

7. Thermal (heat) - energy

- energy stored in the bonds of molecules and released during a chemical reaction.

- energy stored in the nucleus of an atom.

- caused by the movement of particles (atoms and molecules) in an object.

– The faster they move, the more heat energy.

What type of energy do these have?Don’t write – just decide each.

Law of Conservation of Energy

- Energy can’t be created or destroyed. It can only be: transferred or transformed (converted).

A. Transferred-energy moves from one object to another but stays the same type of energy.

B. Transformation or Conversion-energy is changed into a different type of energy.

Is this an example of an energy transfer or an energy conversion?

Energy Lab• Rotate thru the stations.• Draw an energy diagram for the object at each

station.• You get 3 minutes at each station to draw your

energy transfer diagram.
