1. Warm Up 1. What is the independent variable”
What is the dependent variable?
What is the relationship between the # of pizza toppings and cost of the pizza?
How much does a pizza with 3 toppings cost?
**MATH** What is the slope of this line?

2. Energy Energy is the ability to do work.
Work is a transfer of energy.
Energy and work are expressed in units of joules (J).

4. The two main forms of energy are:
Potential energy- stored energy that can be put into future use
Kinetic energy- the energy of motion.

5. The two main forms of energy are:
Potential energy
Chemical
Nuclear
Kinetic energy
Electromagnetic (light)
Thermal (heat)
Sound
Electrical
Mechanical (motion) mechanical (position)

6. Mechanical energy is the total energy of motion and position of an object.
mechanical energy  potential energy  kinetic energy

8. More mass and/or higher velocity = more KE
More mass and/or higher above the ground (resting position) = more PE

9. 22. Use the diagram to answer the question below.
Each ball has the same mass. Which ball has the greatest potential energy?
Ball A
Ball B
Ball C
Ball D

10. Thermal Energy is the energy of moving molecules
All matter has thermal energy
Higher temperature = more KE

12.
matter-basics

13. Electrical Energy - the energy of moving electrons.

14. Sound Energy – moves through vibration of matter
Travels in waves
MUST have matter to travel through

15. Seeing Sound Waves

16. Electromagnetic Energy is produced by the vibrations of electrically charged particles.
Travels in waves
Does NOT need matter to travel
Examples: light, x-rays, microwaves

17. Compare/Contrast: Light and Sound
Kinetic energy
Needs matter to travel
Doesn’t need matter to travel
Travel in waves
Happen because particles vibrate

18. Chemical Energy –stored in bonds between atoms
Examples: food, fuel, batteries

20. Nuclear Energy – stored in nucleus of an atom
Fusion- nuclei join
Fission- nucleus is split
Example: sun creates light/heat through fusion of hydrogen nuclei into helium
