- do spinning objects actually fall slower ?
From the frame of reference of the spinning object, or from that of an outside observer?

And what would happen is you fixed a piece of buttered bread buttered-side-up to the back of a cat, and dropped it from the Leaning Tower of Pisa? Would it land buttered-side-down, or on its feet? And if you dropped it in a box, would Schroedinger expect it to be in a buttered-side-down or feet down position before he opened the box? ;)

My prediction is that if you fixed a piece of buttered bread buttered-side-up to the back of a cat, and dropped it from the Leaning Tower of Pisa it would likely land on its head.

Adding jam or using a muffin may confound the results.

I was reading through this thread on Saturday afternoon, and man, that painted figure in your animated video made its appearance at some point in a dream I had last night...

I can't really say that it was nice, but I can assure you it's been one of the most extraordinary dreams I've ever had.

Hopes are on not to dream of that spinning toast-cat, now...

Hi Raaaid,
what exactly is this "terminal velocity of a parachutist vs a car"? Is that the speed which when exceeded by a parachutists who is going to hit a car terminates his life?

Are you searching for the correct formulas for two cases?
1) The parachutist is falling down through the air and hits the car
2) The car is moving horizontally and hits the parachutist after he has landed

Well i have no mathematical proof but regardless friction they'll be the same.

Dunno... put the parachutist and the car (or a feather and a rock) in a vacuum and they'd both (if released at the same time) hit the deck at the same time?
