What you need:
A bicycle and a friend to ride it.
What you do:
• Ask your friend to cycle fast.
• Watch the upper and lower spokes of the wheels.
What you find:
The spokes of the wheels that are below are clearly visible but the upper spokes are a blur. Does it mean that the top of the rolling wheels moves faster than the bottom?
Yes. This happens because while the wheels are rotating on their axle, they are also moving forward along with the axles. At the top, the two motions are in the same direction but at the bottom the rotation is in the reverse direction.
