i apply a contact force on a rough horizontal surface and it has constant magnitude . now my question is what happens to the angle between the force and the vertical is decreased when i apply frictional force between the surface and the body

Best ResponseYou've already chosen the best response.6Force of friction is equal to the normal force times a constant of the materials. F = N*u. If you reduce the angle with the surface, you decrease the normal, so you decrease the force. That’s logic because think that when you press with angle, the X component (along the surface) doesn’t approach more the particles between the bodies, but the Y component does, so it makes harder to move along any direction.

Best ResponseYou've already chosen the best response.0Unless you are pulling rather than pushing, of course, then the normal force gets smaller for a given pull as the angle above horizontal increases by the factor F sin(theta)
