eli5 how a complete rotation of wheel measures the length of circumstance with the same rotation the inner portion having less circumstance also covers the same distance.

Question

Sorry circumference.

In: 0

Answer 1

The only reason why the inner portion covers the same distance is because it is the part of the larger wheel. If you had a wheel that was only the smaller portion in total size, it would cover a smaller distance.

The distance traveled is essentially the amount of wheel that touches the road/surface that the wheel is traveling on (which is the outermost part of the wheel which has the largest circumference/radius)
