1. Using the graph above, identify the
following:
a. Independent Variable: Time
c. Average Speed: Total distance over
total time.
8. Define acceleration: Change in speed or
direction (velocity) over time
b. Dependent Variable: Position
c. Responding Variable: Position
d. Manipulated Variable: Time
2. What does the slope of the line in the above
graph represent? Speed
9. What is the formula for acceleration?
A = Vf – Vi/t
10. Define the three types of acceleration:
a. Positive Acceleration: Velocity
increasing
3. What is the definition for speed? The
distance over time
b. Zero Acceleration: constant velocity
4. What is the speed of an object at rest? 0m/s
c. Negative Acceleration: velocity
decreasing
5. What is the formula for speed? S = d/t
6. What is the definition for velocity? Speed
included direction
11. List the common units used to measure the
following:
a. Distance: m
b. Time: s
c. Speed: m/s
7. Define the three types of speed:
a. Constant Speed:stays the same as
time goes
d. Velocity: m/s with direction
e.
Acceleration: m/s2

12. You are driving at a constant speed using the
cruise control in your car. You go around a
curve. Did you change your velocity? Did
you accelerate?
Yes you change direction; velocity change, and
yes you accelerate

Which runner moved with a constant velocity the entire race?
Cy Falls . He has 0 acceleration.
2.
Which runner moved with a constant acceleration the entire race? Cy fair because
every second his velocity increases 0.5m
3.
Which runner shows both a positive and a negative acceleration during the race? Cy
Springs because his velocity goes up then goes down .
4.
Which runner had the greatest acceleration over the first 2 seconds of the race? Cy
springs because he went from 0.8 m/s to 1.5 m/s
