Speed Trap Lab

The Speed trap lab we did on the very first day of school. We made chalk lines that were 30 +/- 1 m apart, and we timed how long cars took to go front tire to front tire across the lines. We estimated the uncertainty of distance and time. We calculated speed in m/s and mph, and then we also calculated the range of uncertainty that the m/s had.

Here is a video that shows how to calculate the speed in m/s and then convert that to mph:

Here is a video that shows you how to calculate the range of uncertainty:

Be sure that you show the uncertainty calculation for at least two of the speeds, but calculate all of the max and min values for the different cars.
