How does mass effect contact force?

Mass affects the gravitational force between two objects, as described by Newton's law of universal gravitation. The greater the mass of an object, the stronger its gravitational pull on other masses, which influences how they interact. Additionally, in terms of contact forces, mass affects the normal force and frictional force; heavier objects exert a greater normal force, increasing friction when in contact with a surface. This interplay of mass and force is crucial in determining motion and stability in physical systems.
