Does required time for free falling bodies is independent of mass?

AI Thread Summary
The discussion centers on the idea presented by Professor Walter Lewin regarding the potential dependence of free fall time on mass, despite conventional physics asserting it is independent. Some physicists are conducting experiments to explore this possibility, which, if proven, could challenge established theories like General Relativity. Currently, no evidence supports the notion that mass affects free fall time, but the possibility remains open for future discovery. The implications of such a finding would be significant, potentially warranting a Nobel Prize for the discoverer. The conversation highlights the ongoing inquiry into fundamental physics principles.

In a class at OCW 8.01 Professor Walter Lewin said...

"...there are very prestigious physicists who even nowadays do very fancy
experiments and they try to demonstrate that the time for an apple to fall does depend on its mass even though it probably is only very small, if it's true but they try to prove that. And if any of them succeeds or anyone of you succeeds that's certainly worth a Nobel Prize."

What did he actually mean? Really?! Is it possible to proof that time required for free falling of bodies is not independent of mass?

We don't know. It has not been observed yet, but it could be observed in the future.
IF there is any deviation (that is a big if), it would mean that General Relativity is wrong.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
