Force is classified into two categories: Contact forces and action at a distance forces. These two groups have elements of their own.
Contact force
A force accomplished, when two objects are in contact with each other. Simply kicking a soccer ball, taking a drink of water or even walking requires contact force. For more information on contact forces Click Here
Action -at- a distance force
Force at a distance is the attraction/repulsion between two objects when they are not yet in contact. A magnet can move a pair of keys without even touching them. When you go to lay down on your bed, the force of gravity is acting on you by exerting a downward force,in order for you to lay down. While the bed is exerting an upward for in order to prevent you from crashing to the ground. For more information on Action at a distance forces Click Here
