Based on the graphs in images 3, 4, and 5, what is the relationship between the steepness of the line and the speed of the object?

Open Ended

Explain how you can determine the speed of an object from a distance vs time graph.

Multiple Choice

Which of the following best describes the motion shown in the first distance vs time graph?

• Stationary (not moving)

• Moving away from the zero mark

• Moving towards the zero mark

• Accelerating

Multiple Choice

Compare the graphs in images 0 and 1. What is the main difference in the object's motion represented by these graphs?

• Object is stationary in both graphs

• Object moves towards zero mark in image 1, stationary in image 0

• Object moves away from zero mark in image 1, stationary in image 0

• Object accelerates in image 1, stationary in image 0

Open Ended

Open Ended

Explain how you can determine when an object is moving fastest by looking at a distance vs time graph.

Multiple Choice

Which of the following statements best describes what a distance vs time graph shows about an object's movement?

• It shows how far an object travels over a period of time.

• It shows the object's speed at a single moment.

• It shows the direction of the object's movement only.

• It shows the object's acceleration at every point.
