"Get in Gear" and "Gears and Speed" - Experience (Comment)

I've only just completed the two activities ("get in gear" and "gears and speed) recently; furthermore, it proved to be significant in my understanding of gears and can be useful in future projects/activities.

"Get in Gear"
- the activity introduces gear ratio. Gear ratio is the ratio of the driven gear to the driving gear; this is significant to my understanding as it plays a main role in the robot's speed and strength (depending on its setting or ratio).
- probable gear ratios and benefits:
1:5 = small driven gear and big driving gear
5:1 = big driven gear and small driving gear
1;1 = both driven and driving gear have the same amount of teeth = motor's speed

"Gears and Speed"
- the activity focuses on calculating speed in relation with gear ratio of a robot. It introduces two hypotheses that presumably is able to calculate the correct speed: however, only one of them is correct, so i had to experiment both hypothesis (compare with average speed)in order to find out which one is correct. In the end i found out that hypothesis B was correct.
- Hypothesis B ( speed 1 * gear ratio 1 = speed 2 * gear ratio 2) is approximately the average speed of the the three trials.

Formulas:
Gear Ratio = driven gear/driving gear
Hypothesis A (incorrect) = (speed1/gear ratio1)=(speed2/gear ratio2)
Hypothesis B = (speed1*gear ratio1)=(speed2*gear ratio2)
