Constant Velocity: Velocity-Time Graphs
Directions:
On this worksheet you will practice working with velocity-time graphs for "constant velocity."

Question 1
The y-axis, representing velocity, is scaled so that each square (vertical division) represents
9 m/sec.
The x-axis is scaled so that each square represents
1 second
