Gears and Speed invistigation

In the gears of speed investigation we had two Hypotheses

First we find a value that we could compare the other values to. That means we tried to find Speed 1 and we used a number with the wheel ratio of 1 and running for 3 sec for gear ratio 1. We then measured the length of how long it traveled and the calculated the speed of the robot.

After predicted what the speed of speed 2 would be if gear ratio 2 is larger then 1 or smaller then 1. in both Hypotheses


When we tested how fast it went if the gear ration is larger or smaller then 1 we found that the values where closer to the prediction of hypothesis B. Then we reached the conclusion that hypothesis B is true and Hypothesis A is false
