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
 
Physics news on Phys.org
the collision impulse between the atoms is because of the electormagnetic repulsive forces between them.
 
ahh i see, thank you.
 
Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
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...
