Classwork: Graphing Motion
1. A car travels at a constant velocity of 20 m/s north for 10 s.
a. Complete the table showing the car’s displacement at the end of each second. Then graph the motion
(displacement vs time). Be sure to label the x-axis and y-axis, and include units!!

b. What is the slope of the line, and what are the units for the slope? SHOW WORK!
c. How does the value of the slope compare to the velocity stated in the question? EXPLAIN YOUR
ANSWER!
d. Complete the table showing the car’s velocity at the end of each second. Graph the velocity vs time.
Be sure to label the x-axis and y-axis, and include units!!

2. Complete each sentence with a physics vocabulary word:
a. The slope of a displacement vs time graph represents _________________________________.
b. The slope of a velocity vs time graph represents _________________________________.
3. A toy train moves along a straight portion of track in the following manner:
 After two seconds of traveling at a constant velocity in the positive direction, its position is 4.0 cm.
 After three additional seconds of traveling at a different constant velocity, its position is 5.0 cm.
 It travels an additional 5 seconds at yet another constant velocity, and now its position is 10.0 cm.
a. Draw a graph representing this situation. Be sure to label the x-axis and y-axis, and include units!
b. Which time interval of the journey had the greatest velocity? Justify your answer with specific data from
your graph.
4. Notice that this is a VELOCITY vs Time graph. Use the graph to circle one word/phrase from each set:
a. Segment A:
Circle one: Constant speed, Stopped, Accelerating
Circle one: Forward, Backward, Forward to
Backward, Backward to Forward
Circle one: Slow, Fast, Slowing down, Speeding up,
Slow down/turn around/speed up
b. Segment B:
Circle one: Constant speed, Stopped, Accelerating
Circle one: Forward, Backward, Forward to
Backward, Backward to Forward
Circle one: Slow, Fast, Slowing down, Speeding up,
Slow down/turn around/speed up
c. Segment C:
Circle one: Constant speed, Stopped, Accelerating
Circle one: Forward, Backward, Forward to
Backward, Backward to Forward
Circle one: Slow, Fast, Slowing down, Speeding up,
Slow down/turn around/speed up

How did class go today? Did you get a lot of work done? Do you think you and your classmates met Ms. Breaux’s
behavior expectations? (at least 2 lines)
