10. Negative Acceleration (deceleration)
11. No Motion (stopped)
12. Moving Backwards (constant velocity in reverse)
Graph A matches description No Motion because distance did not change.
Graph B matches description Constant Speed (high rate of speed) because graph is linear and steep.
Graph C matches description Moving Backwards (constant velocity in reverse) because graph has a
negative slope and is linear.
Graph D matches description Acceleration because graph is getting steeper.
Graph E matches description Negative acceleration (deceleration) because graph is getting less steep.
Graph F matches description Constant Speed (low rate of speed) because graph is linear and not steep.

Teacher Tip: On the last page, the graphs measured “distance” on the y-axis. On
those graphs, a flat line meant that the distance was not changing, so it represented
“no motion.” Here, the graphs measure “speed” on the y-axis. A flat line here means
that the speed is not changing. This could represent cruise control when you are
driving at a constant speed on the freeway, or it could (as in Graph D) represent a
constant speed of zero.
Use the graph to the right to answer the questions below.
Which runner won the race? Albert
Which runner stopped for a break? Charlie
How long was the stop? 5 seconds
