    Friction Gravity
AI Thread Summary
In a scenario without friction and gravity, a table tennis ball would still bounce off a paddle rather than pass through it, as the solidity of objects is not dependent on these forces. The absence of friction means the ball would not slow down upon impact, and without gravity, it would not fall after bouncing. The discussion emphasizes that the fundamental properties of matter allow for solid objects to interact without being influenced by these forces. Overall, the interaction would remain intact, but the ball's motion would be significantly altered.

If there was no friction and gravity...

If a table tennis ball hits the paddle, what would happen? Would it go right through it?

No. Friction and gravity have nothing to do with why an object is solid.
 
It would bounce off. It just wouldn't slow down till it hit something else, and it wouldn't fall.
 
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...
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...
