How long did it take this object to travel 10 m?

• 0 s

• 10 s

• 15 s

• 20 s

How long did it take this object to travel back to its reference/starting point?

• 20 s

• 30 s

• 60 s

• 100 s

An object travels at constant speed, and its distance and time are shown in the graph. Using the formula S=d/t, find the average constant speed of the object between 3 and 5 seconds. 

• 25 m/s

• 50 m/s

• 150 m/s

• 300 m/s

Students record information about the motion of an object in a straight line. They record their measurements in the table. Using the formula S=d/t, find the average speed of the object.

• 3 m/s

• 9 m/s

• 18 m/s

• 36 m/s

Students prepare to graph an object's information from the data table . They make the graph with time on the x-axis and distance on the y - axis. How would this object's motion appear on their graph?

• a line that curves downward

• a flat line that does not slope up or down

• a straight line that slopes upward

• a line that curves upward

Students record information about the motion of an object in a straight line. They record their measurements in the table. Which of the following provides the strongest evidence that the forces on this object are balanced?

• The object’s’ motion is measured in meters per second

• The distance the object moved increases over time.

• The object’s motion is not changing.

• The object stopped moving at the end of this time period.
