Distance-Time and Velocity-Time Graphs

Use the student exploration guide to investigateĀ distance-time and velocity-time graphs.

Interpreting Graphs

You may either complete the assignment on your computer or print the assignment and then scan your answers.

Instructions:

Write your name on every page.

Complete all of the problems below.

Be sure to show all the steps in your solution.

When you are finished, submit your work for evaluation.

1. Answer the following questions by referring to the graph below.
1. At what time(s) is the object not moving?
2. During which time interval is the object moving with a constant velocity?
3. During which time interval does the object have a negative acceleration?
4. What it the object’s average acceleration between t = 6 s and t = 14 s?
5. What is the object’s displacement between t = 0 s and t = 8 s?
6. The displacement of the object between t = 17 s and t = 19 s is -8 m [N]. Explain how it is possible, in this problem, to have a negative displacement.
7. The diagram below shows the motion of a ball. It rolls along the floor, up a ramp, rolls back down the ramp, and back along the floor. While looking at the diagram, consider how the velocity of the ball will change throughout the journey.

The v-t graph below shows this motion.

1. During which time interval is the ball:
1. Rolling forwards along the floor?
2. Rolling up the ramp?
3. Stopped at the top of the ramp?
4. Rolling down the ramp?
5. Rolling backwards along the floor?
2. What is the acceleration of the ball when it is:
1. Rolling up the ramp?
2. Rolling down the ramp?
3. Stopped at the top of the on the ramp?

How far did the ball travel before it began to roll back down the ramp?

1. What is the total displacement of the ball over the entire 12 s trip?
