through the air at 10 m/s
8. Use the following information to label the skateboard ramp.
a. Use the letter “P” to label the area(s) on the ramp where you would have the maximum
potential energy.
b. Use the letter “K” to label the area(s) on the ramp where you would have the maximum kinetic
energy.
c. Use the letter “I” to label an area on the ramp where kinetic energy is increasing.
d. Use the letter “D” to label an area on the ramp where kinetic energy is decreasing.
P

9. Fill in the following chart with the six forms of energy:
Type of Energy
Chemical Energy
Nuclear Energy
Mechanical Energy
Electrical Energy
Light Energy
Heat Energy
Definition
Is potential energy that is stored in chemical bonds that hold molecules
together.
Is stored in the nucleus of an atom.
Is the movement of objects and substances from one place to another.
The energy associated with electric charges and their movements
Is radiant energy that travels in waves and you can see it.
Heat energy transfers by particles bouncing into each other.
10. Draw energy transformation diagrams for the following:
1. You put gasoline in your car and then drive away.
Chemical energy

Mechanical energy
2. You turn on your electrical stove and begin cooking.
Electrical energy

Heat energy
3. Millions of years ago, the Sun was shining on ancient plants and animals. The remains of
those plants and animals became coal over millions of years. Today, we burn the coal as a
fuel source.
Light energy

Chemical energy
11. What is the main energy source for all things on Earth?

Heat energy
Sun
Sun
12. The amount of energy coming in from the ____________________
is approximately
____________________________to
the amount of energy being sent back out into
Equal
____________________________.
Space/Atmosphere
13. Label the following electromagnetic spectrum with the following information:
Infrared
Wavelengths are getting longer
Visible Light
Ultraviolet
Wavelengths are getting shorter
a. Visible light
d. Wavelengths are getting longer
b. Ultraviolet light
e. Wavelengths are getting shorter
c. Infrared
14. What is the difference between all of the different types of energy on the electromagnetic spectrum
(the difference is NOT color)?
The size of the wavelengths.
15. Give two examples of surfaces that would REFLECT a lot of energy from the Sun.
Snow
Water
16. Give two examples of surfaces that would ABSORB a lot of energy from the Sun.
Pavement
Soil
17. Describe Earth’s CURRENT energy budget (discuss the amount of energy coming in from the Sun
compared to the amount of energy leaving Earth).
Currently, the amount of energy coming in from the Sun is EQUAL to the amount of energy
leaving Earth. If we were to RECEIVE MORE than we are GIVING BACK, our temperatures would
INCREASE.. If we were to GIVE BACK MORE than we are RECEIVING, our temperatures would
DECREASE.
