This experiment suggests that ball B will reach the goal faster than ball A although the balls have identical properties and they start from the same height. An increase in velocity of the ball more than compensates the increase in length of the path: buff.ly/3bXvnox

One reason could be that the ball on wavy track might not be in contact all the time and hence frictional forces are lower

Question: does this indicate that a road with hills could be more energy efficient for cars than a straight one (if there were no speed limits but speed was instead allowed to fluctuate on both sides of the limit)? Seems absolutely counter intuitive. :o

this means cycling in a hilly environment goes faster than cycling in a flat environment.

One way to understand this is to imagine ball B drops into just one dip instead of four. It will have a greater horizontal velocity than ball A and thus will reach the other side faster. Changing it to multiple dips will slow it somewhat of course.

Isn't that like skipping a stone on water? The premise is the same. Correct?

Our Indian Bihar state government had implemented it.
