1
3. Consider the position vs. time graph below for bikers A and B:
a. Do the bikers start at the same point?
How do you know? If not, which is
ahead?
b. At t = 7 seconds, which biker is ahead? How do you know?
c. Which biker is traveling faster at t = 3 seconds? How do you know?
d. Are the bikers’ velocities equal at any time? How do you know?
e. Physically, what is happening at the intersection of lines A and B?
f. Draw a motion map for bikers A & B:
Biker A:
Biker B:
2
4. Consider the position vs. time graph below for bikers A and B:
a.
How does the motion of biker A in this
graph compare to that of biker A in
question #3?
b. How does the motion of biker B in this graph compare to that of biker B in question #3?
c. Which biker has the greatest speed? How do you know?
d. Describe what is happening at the intersection of lines A & B?

5. In order to rank the following, you may need to look at your notes for the difference between
displacement and distance traveled.
B
C
A
D
E
F
a. Rank the graphs according to which show the largest magnitude of displacement to the smallest
magnitude of displacement from the beginning to the end of motion. (Ties are possible).
Largest
1______ 2 ______ 3 ______ 4 ______ 5 ______ 6 ______
Smallest
Explain the reasoning for your ranking:
b. Rank the graphs according to which show the largest distance traveled to the smallest distance traveled
from the beginning to the end of motion.

6. Sketch the velocity vs. time graphs and the motion maps corresponding to the written descriptions of
the motion of an object.
a. The object is moving in the positive direction at a constant (steady) speed.
b. The object is standing still.
c. The object moves in the negative direction at a steady speed for 4s, then stands still for 4s.
d. The object moves in the positive direction at a steady speed for 4s, reverses direction and moves back
toward the negative direction at the same speed.
