Motion Graphs Practice
Directions: For the following problems, select the best choice that answers the question.
The graph below represents the relationship between the displacement of an object and its time
of travel along a straight line.
1. What is the magnitude of the object’s total displacement after 8.0 seconds
A) 16 m B) 8 m C) 2 m D) 0 m
2. What is the average speed of the object during the first 4.0 seconds
A) 2 m/s B) 0 m/s C) 8 m/s D) 4 m/s
3. Which pair of graphs represent the same motion
A) C)
B) D)
4. Which graph best represents the motion of an object whose speed is increasing
A) B) C) D)
Directions: For the following problems, answer using complete sentences and the GUESS method
where appropriate. Show ALL work.
5. The graph below represents the motion of a body moving along a straight line. According to
the graph, which quantity related to the motion of the body is constant __________________

6. The graph below represents the relationship between distance and time for an object. What is
the instantaneous speed of the object at t = 5.0 seconds
7. The diagram below shows a worker moving a 50.0 kilogram safe up a ramp by applying a
constant force of 300. Newtons parallel to the ramp. The data table shows the position of the
safe as a function of time.
a. Using the information in the data
table, construct a line graph. Plot
the data points and draw the
best-fit line.
b. Calculate the slope of the best fit
line. Show ALL work using the
GUESS method.
c. Using one or more complete sentences, explain the physical significance of the slope
of the graph.
