I have been wondering, and curious as well, and thus I would like to ask: Generally, are acceleration as in reaching top speed or zero speed from top speed and acceleration in terms of changing direction equally easy for human beings at average and normally, or is changing speed easier than changing direction or vice versa?
Don't get me wrong, I know it is a possibility that humans can achieve both easily; wait, scratch that! I mean more of a certainty than a possibility, maybe, but even then, I have always thought there was a difference, with acceleration being an increase in speed over time, with speed being distance covered over time, and turning; as in centripetal acceleration, as I am describing change in direction here; which is, velocity or speed squared divided by radius. That has made me think there is a difference in the past. Of course, I could be wrong, I know.
But the question I want to ask is mainly this: Which, in terms of acceleration do humans find to be easier to do than the other? Is it change in speed, change in direction, or are both equally easy? Since this is a human doing the acceleration, I would say we are talking about a human changing speed or direction as they are running here. I am asking because I just want to make sure.
