5 quick questions — pick an answer to see if you’re right.
1. What does the slope of a displacement vs. time graph represent?
2. An object's displacement is 5.0 m at 2.0 s and 10. m at 4.0 s. What is its velocity?
3. An object's displacement goes from 15 m to 5 m in 2 s. What is its velocity?
4. A displacement vs. time graph shows a flat, horizontal line. What is the object doing?
5. Two displacement vs. time graphs both show increasing displacement. One is a straight sloped line. What does that line show?
Walking the Dog
A student wore a GPS watch while walking his dog along a straight path. Graph 1 shows his distance from home over 40 seconds. Sections of the graph are labeled A, B, C, and D.

C1. During which section was the student moving toward home?
C2. A student makes the following claim.
Place a check mark in either the Support or Refute box. Justify your response using a mathematical relationship.
C3. Substitute numerical values from Graph 1 into a mathematical representation that can be used to determine the student’s speed during section A. Then calculate the speed.
C4. For the full 40 seconds, what were the total distance traveled and the displacement?
C5. Determine the magnitude of the student’s average velocity from 0 s to 25 s.
C6. At the end of the 40 s, the student’s fitness app reported “0 m traveled.” Using Graph 1, identify the quantity the app actually reported, and describe how the app should calculate the distance he walked.
