Why the object actually rotates ?
When I researched about this topic , I have gotten satisfying answer from here: Why do object rotate at all?
All the atoms and molecules of the object are connected with each other by intermolecular force. So when we apply force on the object other than its centre of mass these force oppose the motion and result in the rotation.
My question is : if all the atoms and molecules are bind by intermolecular forces , then why the half of the portion of the object moves in opposite direction (i.e , why the half the part of object rotates in the direction of force and other half rotates in the opposite direction of force)
So what am I missing here?
