Potential vs. Kinetic Energy
Sample Question for SS 6.8A:
1. The drawing above shows a diagram of the Steel
Dragon 2000, a roller coaster in Japan. It is one of
the longest roller coasters in the world. At which
point on the roller coaster would a rider have the
greatest gravitational potential energy?
A. W
C. Y
B. X
D. Z
Calculating Average Speed
Sample Question for SS 6.8C:
Students in Mrs. Parker’s class placed a steel ball at the
top of a long ramp. As the ball rolled down the ramp,
the students measured the distance the ball had
traveled at various times. The graph above is a record of
their measurements.
2. What is the average speed of the steel ball
between 3 seconds & 5 seconds of the
investigation?
A. 2.0 m/s
C. 6.5 m/s
B. 4.0 m/s
D. 14.0 m/s
Measuring Changes in Motion
Graphing Changes in Motion
Sample Question for SS 6.8D:
3. The graph shows the speed of a car traveling east
over a 12-second period on a flat surface. In the
first 6 seconds shown on the graph, the car is:
A. increasing its speed.
B. changing direction.
C. heading northeast.
D. gaining potential energy.
Energy Transformations
Sample Question for SS 6.9C:
4. In the diagram above, a wind turbine is
transforming energy from the wind. Between which
two steps in the diagram is mechanical energy
being converted into electrical energy?
A. 1 & 2
C. 3 & 4
B. 2 & 3
D. 4 & 5
Unbalanced Forces Change the
Speed or Direction of an Object’s
Motion
Unbalanced Forces…
Sample Question for RS 8.6A:
5. A toy train engine rests motionless on a track. One
student begins pushing the engine to the right with a
force of 2 Newtons. At the same time, another student
begins pushing the engine to the left with a force of 5
Newtons. Which of the following best describes the
resulting motion of the engine?
A. The train will travel left at a constant speed.
B. The train will travel left at an increasing speed.
C. The train will travel right at a constant speed.
D. The train will travel right at an increasing
speed.
Speed vs. Velocity vs. Acceleration
Sample Question for RS 8.6B:
6. A student is walking home from school. After 5 minutes it
starts to rain lightly, so the student walks a little faster. After
another 2 minutes it starts to rain hard, & the student runs the
rest of the way home. The total time the student takes to get
home is 10 minutes. Which graph below best represents the
student’s motion during the trip home?
A.
C.
B.
D.
Sample Question for RS 8.6B:
7. At which points is the velocity of the car the
same?
A. Points A & B C. Points B & C
B. Points A & C D. The velocity is not the
same at any of the points.
Sample Questions for RS 8.6C:
8. In a series of controlled experiments, a student measures
the force acting on a wheeled cart & the cart’s acceleration.
The student’s data are shown here:
Based on the recorded observations, what is the mass of the
cart in kilograms. Record & bubble in your answer in the
griddable on your answer document.
9. When pressure is released during an earthquake,
the type of energy displayed would be:
A. kinetic energy.
B. potential energy.
C. gravitational energy.
D. inertial energy.
Sample Questions for SS 7.7A:
10. Miranda walks up to home plate with
her bat, stands with her bat in the air,
swings her bat, & makes contact with the
ball. In which part of this situation is no
work occurring?
A. batter walks up to home plate with
her bat
B. batter stands with her bat in the air
C. batter swings the bat
D. batter makes contact with the ball

is moved 4 meters?
A. 0.5 Nm
C. 4.0 Nm
B. 2.0 Nm
D. 8.0 Nm
