All information is gather through a vartiry of resources and is only here to help my students with classroom instruction

2. Warm - up
• What temperature on the
Celsius scale is equivalent to
373K?
• Which temperature is colder 0 F
or 200 K?

3. What is Energy?
Different Kinds of
Energy

4. What is Energy?
•The ability to do work.

5. Can you make
things move?
•Then you have
energy…
•…but there are seven
different kinds of
energy…

6. Chemical Energy
•What holds atoms in
molecules together
•Can be released by
chemical reactions like
burning wood

9. Electrical Energy
•The movement of
electrons through
matter
•Electricity is a form of
electrical energy

12. Heat Energy
•The random motion, or
vibration, of atoms in
matter
•The faster the atoms
vibrate the more heat
energy they have

14. Light Energy
•The vibrations of
electrically charged
particles
•Yes, whenever you are
looking at light, you are
looking at energy

17. Mechanical Energy
•Total energy of motion
and position of an object
•ME=PE+KE
•When you ride a bike
you use mechanical
energy

20. Nuclear Energy
•Holds protons and
neutrons together in an
atom’s nucleus
•Powers the sun and
nuclear power plants

24. Sound Energy
•Vibrates air molecules
•The air molecules move
tiny bones in your ear
•The message of sound
then moves to your brain
•Can also vibrate objects

27. Energy can be changed
from one form to another
•Chemical energy in
gasoline is changed to
heat energy and then
to mechanical energy
in a car
•Law of Conservation of

32. Gravitational Potential
Energy
• Gravitational potential energy=
weight x height
• Measured in Joules (J)
• Gravity = 1
