STUDENT VERSION

2. Power = Work / Time… P=w/t
Define Energy:
Power = Work / Time… P=w/t

3. Work has 3 requirements – what are they?1. 2. 3.
Work = Force x distance… W=Fd

4. Define: Kinetic Energy (ke)

5. Define: Potential Energy (PE)

6. Leopard has POTENTIAL ENERGY WHEN….

9. amount of time it takes to make one trip from side to side
Period
amount of time it takes to make
one trip from side to side

13. Define: Mechanical energy:
ME = PE + KE
An airplane soaring through the sky has mechanical energy just like the wind or a flowing river.
Sound is another type of mechanical energy.

14. Define: Chemical Energy
The food you eat gives chemical energy which allows you to walk, run and move.

15. Define: Electrical Energy
It can come from batteries or power plants and it can also be found in nature.
Power plants burn fuel to make electricity which is then sent to homes and businesses through wires.

16. Plants use it to make food. Scientists use it to create lasers.
Light Energy
comes from the Sun.
Plants use it to make food.
Scientists use it to create lasers.

17. Define: Thermal energy
The faster the particles move, the warmer the matter can get.
Examples of thermal energy are stoves and matches.

18. define: Nuclear energy
The Sun’s energy is produced from nuclear reaction.

19. What is the Law of Conservation of Energy?
Total amount of energy never changes.
