Quoted from MT45:3mph is roughly walking speed. Wondering if there are times when it significantly exceeds that? Cool experiment
You can't make direct comparisons between the speed of a human body and a 1 1/8" ball -- you'd have to scale the speed to something more comparable. "Walking speed" sounds slow, but your leg traveling 3 feet is much different than that tiny ball traveling 3 feet. Speaking in terms of perception, of course. That's why RC cars and what not often have their speed calculated as relative, so you get a sense of what the actual speed is relative to the size of the vehicle it is replicating.
tl;dr: 3mph sounds slow, but appears fast with a tiny ball traveling within a tiny space.
