Can an object be accelerating and yet -not- moving?

You would eventually understand it. It's just a matter of time invested.
Follow wherever your interests take you. If that question is important to you, I will try to point you in the right direction.

I feel honored

I just thought of this scenario

A car for example , parked

But the Earth is accelerating , rotation

Hence the car is not moving , but is accelerating

That's a good q, North, a matter about which I've long wondered. Whereas the gravity is pulling straight down, isn't any force on account of rotation pulling at a slight angle

Hey! this could be exploited to make flying cars like on the Jetsons!

Hasn't someone already broached the possibility, that is, for some reason gravity quits or the Earth stops rotating

Seems however we're just a bit OT here. "Can an object be accelerating and yet-not-moving?", almost everyone in the affirmative

…..except me, I have this nagging feeling that the ball actually stops up there, and on a purely mathematical basis, namely that its reversal at the top is, though infinitesimal, a stop; a point at which the graph is horizontal



Again I'm no mathematician (as I'm sure you will agree) but I have this intuitional take: Just as there are different kinds of infinities (for instance based on different rates of development), there are also different kinds of zeroes

Sorry, but no. When you throw a ball up in the air and it slows until it stops, at that instant, its velocity is 0, but it's acceleration is 32 ft/sec^2 downwards. An object's may have any velocity paired with any acceleration.

I have Physics degree and taught Physics.

Brandon is 100% correct.
