    A is Friction

    B is Gravity

    Direction is lateral for Friction

    Direction is towards one another for Gravity

    Friction depends on chemical attraction of the surfaces as well as the degree of smoothness or roughness of surface

    Gravity depends on the mass of the objects and their distances.

    As an aside Gravity refers to the Earth's attraction to objects within it's influence. Gravitation is the more correct general term for the force between objects with mass.
