Use the equations below and your understanding of motion
concepts to answer the following questions. Show all your
work on calculations. Use complete sentences on
explanations. Show units on answers and indicate the
direction of all vectors.
ave. speed = distance/time

ave vel. =
displacement/time

ave. accel'n = change
velocity/time

1. If an object is moving in the positive direction and
slowing down, then its velocity is ____________ and its
acceleration is ____________.
a. positive, positive

b. positive, negative

c. negative, negative

d. negative, positive

e. positive, zero

f. negative, zero

2. The motions of five objects  A, B, C, D, and
E  are represented by lines on a positiontime
graph. Write the letter(s) for any object which is
speeding up. List all that apply.


3. Consider this positiontime graph. Various
time intervals are depicted by a letter. During
which time interval(s) is the object accelerating?
List all that apply.


4. The motions of five objects  A, B, C, D, and
E  are represented by lines on a positiontime
graph. Write the letter(s) for any object which has
a positive (and nonzero) velocity. If there is
more than one answer, then list all that apply.


5. On the positiontime graphs below, draw two
lines/curves to represent the given verbal descriptions;
clearly label the lines/curves as A or B.
A Moving in + direction

B Moving in  direction


A Speeding up

B Slowing down


A Moving at constant speed

B Accelerating


6. Use the positiontime graphs below to determine the
velocity of the object.

7. Renatta Oyle is driving rightward (+ direction) at 30
m/s when she suddenly slows down at a constant rate of
acceleration to a rest position in 5 seconds.
a. Identify the direction of the acceleration of
the car. ________________ Explain.

b. Construct a motion diagram (i.e., an "oil drop
diagram") of the car's motion during this braking
period.

c. Sketch a plot of position vs. time
for the car's motion during this braking
period. If the plot should be a straight
line, make it clearly straight; if it
should be curved, make it clearly curved
and curved in the right direction;
etc.



8. Merely be honest and describe something which has been
helpful (if there is anything) in your efforts to learn and
do well in physics. If nothing has been helpful, offer some
suggestions on how something could be made more helpful.

9. Describe all complaints (if any) in the space below.
Use a separate page if needed (ha).
