Position vs. Time Graphs (x vs. t)
Questions 1-15 The graph below represents the motion of a fish moving along a straight-line path for a period
of 20 seconds. The fish begins its motion 1 meter away from a large rock.
1. a) What is the position of the fish at 0 seconds? Draw the position of the rock and the fish on a simple
number line. Indicate your reference point.
b) What is the position of the fish at 4 seconds?
c) What is the displacement of the fish during this time period? D) What was the fishes average velocity
from t = 0s to t = 4 s?
2. a) What is the displacement of the fish between 4 seconds and 6 seconds?
b) What was the average velocity of the fish during this time period?
3. What is the average velocity of the fish between 10 and 12 seconds?
4. What is the average velocity of the fish between 16 and 18 seconds?
5. For what time period is the fish farthest from the rock?
6. What is the fishing doing between between 6 seconds and 10 seconds?
7. When is the fish moving toward the large rock?
8. When is the fish moving away from the rock?
9. What is the average velocity of the fish from 16-18 seconds?
10. What is the maximum speed of the fish?
11. If the fish was traveling at this speed, how long would it take to swim 50 m?
12. What is the total distance the fish traveled from 0 to 20 seconds?
13. What is the displacement of the fish from 0 to 20 seconds?
14. What is the average speed of the fish from 0 to 20 seconds?
15. What was the average velocity of the fish from 0 to 20 seconds?
16. The position-time graph below represents the motion of a dog during a time period of 10 seconds.
Assuming the dog’s position is measured relative to the tree, write a story describing the dog’s motion.
17 On the graph to the right, how far is the object from the reference
point at zero seconds?
18. Is the object moving toward the observer or away from the
reference point for the first two seconds?
19. During which time segment(s) is the object stopped?
20. How far does the object move from 4-6 seconds?
