What is a force?
A force is a push or pull. To open a door you have to push or pull the door. To do this, you have to apply force on the door. A force will always go in some kind of direction. When you push or pull on a doorknob, the  force is in the direction of the push or pull. 
Push
Pushing is the force of an object moving away from you.
