Constant Velocity - Position-Time Graphs

Directions: On this worksheet you will review some of the properties of position-time graphs when the object is moving at a "constant velocity."

Question 1 The y-axis, representing position, is scaled so that each square (vertical division) represents 9 meters. The x-axis is scaled so that each square represents 1 second.
