Marble experiment (referring to momentum)?

AI Thread Summary
When a marble is struck in a row of stationary marbles, the number of marbles displaced on the opposite side matches the number struck. This phenomenon illustrates the principles of conservation of momentum and energy in physics. The discussion emphasizes that for every marble hit, an equal number is displaced, demonstrating predictable outcomes in momentum transfer. An article linked provides further explanation of this effect. Understanding these principles is essential for grasping fundamental concepts in physics.

marbles are kept in a row like OOOOOO
when one marble is hit on one side, one marble is displaced from other side ;
when two marbles are hit on one side, two marbles are displaced on the other side;
and same with three and four marbles ...

WHY the same numbers of marbles are displaced as the number of marbles are hit ??

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...
