Matching. Match the term on the right with its definition on the left.
1. ______ a stationary place that motion is compared to
2. ______ total distance divided by total time, d/t
3. ______ distance covered in a very small point in
time, d/t
4. ______ the actual pathway that you have taken
to get somewhere
5. ______ change in velocity over time, (vf-vi)/t
A. Acceleration
B. Average velocity
C. Displacement
D. Distance
E. Instantaneous
velocity
F. Reference Point
G. Slope
H. Speed
I. Velocity
6. ______ distance and time in a particular direction
7. ______ how slanted a line is, shows rate of change
8. ______ in a straight line, how far you have gone from beginning to end
9. ______ distance and time, no matter what direction you travel
Explain the difference between….
10. Distance and displacement
11. Speed and velocity
13. Velocity and acceleration
Above are 6 graphs of distance (displacement) on the y axis and time on the x. Use
them to answer the following questions. It is possible for more than 1 graph
to show the motion or none of them to.
Which graphs show…
14. _____________________ something moving away from you
15. _____________________ something moving toward you
16. _____________________ something moving at a constant speed
17. _____________________ something accelerating (speeding up)
18. _____________________ something accelerating (slowing down)
19. _____________________ something not moving
Above are 6 graphs of velocity (speed) on the y axis and time on the x. Use them to
answer the following questions. It is possible for more than 1 graph to show the
motion or none of them to.
Which graphs show…
20. _____________________ something moving away from you
21. _____________________ something moving toward you
22. _____________________ something moving at a constant speed
23. _____________________ something accelerating (speeding up)
24. _____________________ something accelerating (slowing down)
25. _____________________ something not moving
To the right is a graph of distance (displacement) on
the y axis and time on the x axis. Use
it to tell what is happening between each
point in as much detail as possible
(moving/stopped, towards/away, fast/slow,
constant/accelerating)
AB
BC
CD
DE
EF
FG
GH
Show what this would look like on a velocity vs. time graph. Don’t worry about
calculating numbers for the y axis, just show an approximate velocity. Be sure
to label each lettered point (where is A, B, C…?).

Solve the following. Please show your work, round to the correct number of sig figs
and use correct units.
40. ______________ An airplane travels 2000 km in a time of 3.5 hours. What is the
plane’s average speed?
41. ______________ How long will it take an airplane to travel 1200 km at an average
speed of 200 km/hr?
42. ______________ A plane accelerates down a runway from rest to a speed of
600 m/s in a time of 25 s. What is the acceleration of this plane?
43. ______________ Starting at 10.5 m/s, a motorcycle accelerates at .500 m/s until it
reaches a velocity of 12.70 m/s. How long did this acceleration take?
44. ______________ A satellite is moving at 459 m/s orbiting the Earth. Earth’s gravity
pulls it back to Earth, accelerating it at 9.8 m/s/s. After 45 second show fast is
it going?
