Objects around us can not move by itself. There must be something to work on it so that objects can move. If you henda sliding wardrobes, cupboards you push it. As a result, these cabinets will go. If there is a crate on the floor is pulled by a rope tied to the coffin, casket will move. Push or pull is called force.
touch force is the force arising between two or more if two objects are touching. Examples of friction force and lift force.
Force did not touch is the force that arises when two objects are not touching. Example: magnetic force, gravitational force and electric force between two electric charges.
