Graph the two slopes from the distance vs. time graph. Be sure to label and scale the axes.
Acceleration
What is the change in velocity from 1 second to 5 seconds?
How much time did it take to change that velocity?
Use factors and tables to find the slope of your graph above.
What is the unit of your slope? What do you think it means?
Could acceleration also be "how fast something gets slower"? What do you think of this question as it applies to the slope you calculated?
