For the first 5 seconds, what is the speed of the turtle?

• 1.8 m/s

• 0.56 m/s

• -1.8 m/s

• 9 m

Answer explanation

The distance of the turtle traveled is 9 meters over the course of 5 seconds. Distance and speed do not have direction and therefore cannot be negative values because negative refers to a direction when describing motion.

What does the slope of a line represent in a distance vs. time graph?

• Acceleration

• Speed

• Time

• Distance

In the context of a distance vs. time graph, what does the rise over run (slope) specifically represent?

• Time over distance

• Distance over time

• Acceleration

• Displacement

If the line on a distance vs. time graph is leveling out, what does it suggest about the object's motion?

• The object is moving away from the reference point at a constant speed.

• The object is coming towards the reference point at a constant speed.

• The object is changing direction.

• The object is slowing down.

On a distance vs. time graph, what does a downward sloping line indicate?

• The object is stationary.

• The object is moving at a constant speed away from the reference point.

• The object is moving at a constant speed towards the reference point.

• The object is speeding up.
