{Thursday September 23} Lesson 2: Kinetic and Potential Energy
Complete this lesson as you complete Lesson 2 in Connexus
Complete the Quick Check
1. What is the difference between kinetic and potential Energy?
Kinetic energy is the energy of motion (it depends on the object's mass and speed )
Potential energy is the energy of position (It depends on the object's position relative to the earth)
2. Watch the video on page 6 in the lesson. Explain how potential energy is affected by:
a. Mass: The
b. Height:
more mass it has,The more it is affected by gravity
Due to gravity ,You have the potential to move
3. Based on the picture below:
a. Which object has the most potential energy: A, B, or C?
b. What evidence do you have to support your answer?
It is the highest and it has the most mass
C
1
4. Why does the total mechanical energy stay the same as kinetic and potential energy change?
Energy can not be created or
destroyed -it can only change forms.So the total amount of energy will not change. The object's
energy will only change from one to another.

5. How does this pendulum demonstrate the law of conservation of energy?
is conserved because potential energy changes into kinetic energy.
a. At what point does the pendulum have the most potential energy? A/E
higher point.
It shows how energy
because it is the
___________
b. At what point does the pendulum have the most kinetic energy?
the lowest potential energy/most speed. __________
c. What happens to the potential energy as it decreases? As
kinetic energy increases.
At point C because it has
potential energy decreases, the

6. Using the image below:
Explain. It is the highest at point C because that
is when it has the lowest potential energy/most speed.
a. When is kinetic energy at its highest?
b. When is kinetic energy at its lowest? Explain.
Kinetic energy is at its lowest at point A because
this is when potential energy is at its highest.
7.
energy on an object? Mass
and Velocity
What two factors affect the amount of kinetic
{Tue & Wed Sep 28 & 29} Lesson 4: Predicting Changes in Kinetic Energy
Complete this lesson as you complete Lesson 4 in Connexus
Complete the Quick Check
8. Which of the following would have the most kinetic energy?
a. A housefly moving at a speed of 5 mph
b. A car driving down the highway at a speed of 80 mph
c. An airplane parked on the runway
9. Explain why you chose your answer to the previous question.
It has more speed than the fly and airplane. The car also has more mass than a moving fly, Giving it
more kinetic energy

Complete this lesson as you complete Lesson 5 in Connexus
Complete the Quick Check
10. If you have a 200kg man and a 50 kg little girl standing at the top of a diving platform that is 8
ft. above a pool. Which person would have more potential energy? Explain why.
The 200kg man has the most potential energy
because he has more mass compared to the girl. The height does not
affect them
11. Describe the potential energy at each letter in the image to the
right:
W) Highest potential
X)A little less than w
Y) A little less than x
Z) The smallest potential

12. A stationary ball has
Kinetic
potential energy. When you push the ball, its energy is transferred to
energy.
Energy was transferred from my hand to the ball,Which
increased kinetic energy due to its speed and decreased potential energy
What happened to the total amount of energy? Stays the same
a. Why did this energy transfer occur?

18. Explain how kinetic energy affects each object as it changes its state of matter:
a) water boiling: This is an example of Convection. Heat is transferred to the water causing the liquid
water molecules to become gas and their kinetic energy increases.
b) popsicle freezing: Heat is removed from the popsicle and it is lower kinetic energy
c) water condensing on the side of a water bottle: Gas molecules cool down and lose energy and
become attracted to the side of the water bottle when they condense and become liquid water molecules

20. How is temperature related to the transfer of kinetic energy? Explain using an example.
As objects heat up, they can transfer their energy to other objects. Temperature is measurement of heat,
which comes from energy.
Example: A
hot spoon will transfer its kinetic energy to your hand. Example: A hot spoon will melt ice
cream, because it has transferred its kinetic energy due to its high temperature
21. A cold can of coke is left on a table at room temperature, after about 15 minutes the can is
covered in condensation. Explain what has taken place by explaining the movement of the
particles.
The cold can attracted the air molecules and when they hit the cold can, they
condensed from a gas to a liquid due to the temperature change of the air
molecules.
