A lot of people know of the experiement where two objects are dropped from an equal height while inside of a vacuum chamber. Regardless of the mass, size and shape of the objects the objects fall at the same rate which is approx 9.8m/s.
Excluding the apparatus variables, such as the the size of the chamber, or the height the objects are dropped from, there are four variables relating directly to the objects themselves: mass, size, shape, and *temperature*.
My question is:
Has anyone ever found any reference to anyone testing how the fourth variable; by dropping objects of equal mass, size, and shape with one cooled and one heated so as to be at vastly different temperatures; effects the rate at which the objects fall, if at all?
I can only find reference to experiments that alter the first three variables: mass, size, and shape -- but all of them completely ignore the temperature of the objects. I can't find any references to experiments where the fourth variable is tested.
And just to clarify, I'm interested in knowing whether or not anyone has ever ACTUALY TESTED THIS, NOT whether or not people think it will or will not have an effect, regardless of what physics theory states.
I would do the experiment myself, but currently do not have the required tools available to do so.
I'm very interested in knowing if anyone can answer this question.
Thanks,
