Walking Lab
1) Did walker 1 accelerate? Explain how you know.
Yes because the graph is not a straight line for walker 1.
2) Did walker 3 accelerate? Explain how you know.
Yes because the line curved up
3) Which walker, 2 or 4, had the faster average speed? How do you know and show your work.
15.01/20= .7505m/s
6.05/20= .3025m/s
Walker 2
4) Would it be more accurate to use speed or velocity in this lab? Explain your answer.
Velocity, because not all the walkers kept going in a straight line
5) If walker 4 continued to walk past 20 seconds, what would happen to velocity? Explain.
If he/she continued to walk past 20 seconds, then when they got back to 0 meters, there would be no speed.
