Gears and Speed


In the gears and speed investigation we had to determine which of the two hypotheses given to use were indeed correct, or at least which had a greater extent of accuracy.

The 2 hypotheses are in the picture to the right.

The correct hypothesis was found by compairing gear ratios and the distance traveled over three seconds of movment with 100% motor power and averaging them to find the average distance traveled, and then dividing by three (the amount of time) to produce the average speed.

The hypothesis was actualy Hypothesis that was correct ended up being Hypothesis B because it had a smaller range of error produced.
