To fully describe the force acting upon an object, you must describe both the magnitude size or numerical value and the direction. Thus, 10 Newton is not a full description of the force acting upon an object. In contrast, 10 Newton, downward is a complete description of the force acting upon an object; both the magnitude 10 Newton and the direction downward are given.
Because a force is a vector that has a direction, it is common to represent forces using diagrams in which a force is represented by an arrow. Such vector diagrams were introduced in an earlier unit and are used throughout the study of physics. The size of the arrow is reflective of the magnitude of the force and the direction of the arrow reveals the direction that the force is acting.
Such diagrams are known as free-body diagrams and are discussed later in this lesson. Furthermore, because forces are vectors, the effect of an individual force upon an object is often canceled by the effect of another force. For example, the effect of a Newton upward force acting upon a book is canceled by the effect of a Newton downward force acting upon the book.
In such instances, it is said that the two individual forces balance each other ; there would be no unbalanced force acting upon the book. To compel someone or something to do something.
