Energy Study Guide
Unit 2—
1. Compare and contrast kinetic energy and potential energy.
2. For the examples below, write in the forms of energy involved in the picture using
the terms “PE” and “KE” to represent potential and kinetic.
a.
b.
d.
c.
3. How do you know when potential energy is being gained?
4. How do you know when kinetic energy is being gained?
5. Re-write the words that describe either potential energy or kinetic energy in the Tchart below: gravitational, carries, stored, moving, stretched, released, position, height,
rolling.
Potential Energy
Kinetic Energy
6. Match the following types of energy with the following clues:
_____________ Nuclear
A. Carries a disturbance through the air in
waves.
_____________ Sound
B. Produced by splitting the nucleus of an
atom.
_____________ Chemical
C. Potential energy stored in the bonds of
atoms of molecules.
_____________ Gravitational Potential
D. Potential energy that depends on
height.
7. What is the energy transformation when you turn a radio on?
8. What does the Law of Conservation of energy state?
9. Define temperature (use Quizlet definition):
10. What temperature does water freeze at? What temperature does water boil at? (Use
the Celsius scale!)
11. Heat is an action, or process. Describe what heat means and the direction it moves in.
12. When objects with two different temperatures are in contact, heating will occur until
they reach equilibrium (the same temperature). Draw arrows that show the
direction that heating will occur in the following pictures:
2 cans at two different temperatures
are placed in a 20&deg;C pot of water.
50&deg;
C
20&deg;C water inside a warming pan on
the stove.
10&deg;
C
20&deg;C
13. How could you graph two objects at different temperatures reaching equilibrium after
time has passed?
14. Define the three forms of heat transfer: THEN make a list underneath each of at least
10 examples of each form of heat transfer. This list will need to be checked by a
classmate!
Conduction
Convection
