What happens in a belt and pulley system?

When one of the wheels is rotated, the belt transmits the motion and makes the other wheel rotate.

Check

Why can friction wheels be subject to wear and tear when they are used over long periods of time?

Because the transmission is obtained through friction

Check

Okay!

Check

For friction wheels, the speed at which the wheels rotate is measured in what?

Revolutions per minute (rpm)

Oops!

Check

Okay!

Check

Does the speed multiply or reduce when the driven wheel is smaller than the driver wheel?

It multiplies, because the smaller wheels have to turn faster than the bigger ones in order to transmit motion
