\r\n \r\n Mathematically, a vector is an entity that has both magnitude and direction.\r\n At first, vectors may seem like a purely mathematical concept.\r\n However, as you will learn in later chapters, vectors are necessary to describe a number of physical quantities such as velocity, force, flux, etc.\r\n In fact, the vectors are so essential in physics that a vast majority of theories in physics and mathematics cannot be described or formulated\r\n without the use of vectors.
\r\n This module on vectors consists of four chapters — an outline of which is given below:\r\n Chapter 1
\r\n In chapter 1, we will review vector form in Cartesian components and polar form (magnitude and direction).\r\n Chapter 2
\r\n In chapter 2, we will discuss the addition and subtraction of two vectors.\r\n Chapter 3
\r\n In chapter 3, we will talk about the scalar (also known as dot) product of two vectors.\r\n Chapter 4
\r\n Finally, in chapter 4, we will concluded the module on vectors with a review of vector (also known as cross) product of two vectors.\r\n
