How do you turn on the EV3?

Press and hold the Left and Right buttons for 5 seconds.

Click on the answer that doesn't describe a mechanism.

Increase the ability to make circular motion

The input speed of a device compared to its output

An idler does this in a simple gear train:

Input & output gears will rotate in same direction
