Where is contact made during collisions?

AI Thread Summary
Contact during collisions occurs at the atomic level due to electromagnetic repulsive forces between atoms. When two objects collide, they do not physically touch in the traditional sense; instead, their electron clouds interact. This interaction creates a force that prevents the atoms from penetrating each other. The confusion often arises from the abstract nature of atomic interactions, as contact is not a tangible point but rather a result of force fields. Understanding this concept is crucial for grasping the mechanics of collisions at both macroscopic and microscopic levels.

If two objects collide with each other, where is contact actually made? This question confuses me because even at the atomic level (two atoms colliding) where is contact made? P.s. i hope I'm in the right section of the forum

the collision impulse between the atoms is because of the electormagnetic repulsive forces between them.
 
ahh i see, thank you.
 

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...
