Get in Gear

1. Yes. The robot went faster.
2. Increasing the motor power would allow the wheels to move faster.
3. If you make the gear of the wheel axle smaller, the robot will go faster. If it is bigger, it will go slower.
4. It went faster. It went twice the distance in the same amount of time. We timed the robot, and saw that it went faster.
5. It will go slower. It went half the distance in the same amount of time.
6. To make it go faster, you can increase the power or swap the wheel gear to a smaller gear.
7. To make it go slower, you can decrease the power or swap the wheel gear to a bigger gear.
8. The larger wheel will go on the motor.
9.
i. same
ii. very slow
iii. To go faster, the gear on the wheel must be smaller than that on the motor. To go slower, the gear on the motor must be smaller than that on the motor. To go the same speed, the gears must be the same size.
iv. If the wheel gear is smaller than 16, it will go faster. If it is 16, it will go the same speed. If it is bigger than 16, it will go slower.
10.
i. It was only set to motor rotations, not wheel rotations. Since the wheel gear was smaller, it rotated more in the same amount of time.
ii. It was only set to motor rotations, not wheel rotations. Since the wheel gear was bigger, it rotated less in the same amount of time.
iii. No. It the wheel gear is smaller, than you will have to figure out the ratio between the motor gear and the wheel gear to figure out how many motor rotations will equal a wheel rotation.
11.
i. small gear on the wheel and large gear on the motor.
ii. large gear on the wheel and small gear on the motor.
iii.  large gear on the wheel and small gear on the motor.
iv. small gear on the wheel and large gear on the motor.
12. Different gears work better for high speeds than they would for towing and having lots of power.
