>>13257160OP here,
on your picture there are straight paths.
Yes, I realize that my opening explanation was retarded, but when I have opened with actual good explanations the thread gets no attention.
The question is really about movement, not about length.
This is the properly formulated question:
The ratio between the time taken to travel at constant speed around a circle and the time taken to travel (at that same speed) for the length of the diameter of the circle along a straight line is 4, not pi. True or false?
You may think the question is retarded, but this experiment is quite compelling. I think he omits to calculate the speed of each ball after the loop/straight path. If the ball has the same speed after the loop as the straight one, then it would be quite impressive.

I have ordered some hot wheels tracks and will post any interesting results
