# Scalar and Vector Quantities in Applied Mathematics

In this post Scalar and Vector Quantities in Applied Mathematics will be explained in detail with example and suitable image or graph.

### Course Details:

Course Name: Applied Mathematics I
Chapter Title: Vectors, Lines and Planes
Subtitle: Scalar and Vector Quantities

A scalar is a quantity that is determine by its magnitude (its number of units measured in a suitable scale).
Examples 1 Mass, length, temperature, voltage are examples of scalar quantities.

Quantities that have both magnitude and direction are called vectors. A vector is usually represented by an arrow, the length of the arrow represents the magnitude of the vector and the arrow head indicates the direction of the vector.

Examples 2 Velocity, acceleration, displacement and force are examples of vector quantities.

When a vector is represented by an arrow, say , the point A is called the initial point (tail) and B is called the terminal point (head) of the vector. Vectors can also be represented by a single letter (usually small letter) with a bar over it such as , etc.
