Non-contact forces generally fall into two categories.the the
Gravity : is a non-contact force between two objects. The force exerted on each body by the other through gravity 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. The direction of the force is from the body acted on towards the body applying the force. A human body's weight is a non-contact force exerted by the Earth on their mass.
Magnetism is a unique non-contact force similar to gravity that generally acts to produce a stronger force over much shorter distances and only affects specific materials. Magnetism can produce a force towards or away from the Magnet .
