An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object.The normal force is the support force exerted upon an object that is in contact with another stable object.(tbh google)
The difference is that applied force is applied onto a person or another object but normal force, is the support force exerted upon an object that is in contact with another stable object.
