Collision, friction, contact?

  1. Jan 6, 2007 #1
    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.
