When we want to open a door, we have to push the door handle with our hand and while closing it we pull the handle of the door. This means to move an object, it has either to be pushed or pulled. A push or pull on an object is called force.

An interaction of one object with another object results in a force between the two objects. At least two objects must interact for a force to come into play.  Suppose a man is standing behind a stationary car. Since there is no interaction between the man and the car, no force acts on the car and hence the car does not move. Now, suppose the man begins to push the car, that is, he applies a force on it. The car may begin to move in the direction of the applied force due to interaction between the man and the car. Note that the man has to push the car to make it move.
