A force is a vector that has both magnitude and direction. True or False?
Force has a well-defined magnitude as well as direction.
Answer: Force is a vector quantity that has both magnitude and direction.
Go through the diagram to understand the concept of the vector.
A vector is a physical quantity that has both magnitude and direction. We can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. Two vectors are the same if they have the same magnitude and direction. This means that if we take a vector and translate it to a new position (without rotating it), then the vector we obtain at the end of this process is the same vector we had in the beginning.
Force is a physical quantity that has both magnitude and direction, hence it is a vector quantity. 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. 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. 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 20-Newton upward force acting upon a book is canceled by the effect of a 20-Newton downward force acting upon the book.
