Gears and Speed Investigation

In the gears and speed investigation we had to decide between two hypotheses as to which one more accurately calculates the distance that the robot will move due to its gear ratio. To do this we measure the distance the robot traveled three times, we repeated this process with a few different gear ratios. We then averaged the distances to decrease the error created during the experiment.
We then used the distances and gear ratios and using the two hypotheses to predict the speed at which the robots moves. We then compared the predicted values with the actual value and decided which of the hypotheses worked best.

We discovered that the hypothesis that works best is Hypothesis B.
