Do the force of friction and other contact forces arise due to gravitaional attraction? If not then what is the origin of these forces?
Dear Student ,
Frictional force arises due to the motion of a body on a rough surface and the direction of force is on the opposite direction of the motion of the body .
Now when other contact forces such as cohesive or adhesive force are also arise due to intermolecular attraction and intramolecular attraction force .
Therefore contact forces never occur due to gravitational attraction .
