A non-contact force is a force which acts on an object without coming physically in contact with. The most familiar example of a non-contact force is weight. In contrast a contact force is a force applied to a body by another body that is in contact with it. All four known fundamental interactions are non-contact forces: Gravity, the force of attraction that exists among all bodies that have mass. The force exerted on each body by the other through weight is proportional to the mass of the first body times the mass of the second body divided by the square of the distance between them.
