Vectors, Additon of Vectors and Components of Vectors

In physics and all science branches quantities are categorized in two ways. Scalars and vectors are used for to define quantities. We can use scalars in just indication of the magnitude, they are only numerical value of that quantity. However, if we talk about the vectors we should consider more than numeric value of the quantities. Vectors are explained in detail below.

Vectors

Vectors are used for some quantities having both magnitude and direction. We will first learn the properties of vectors and then pass to the vector quantities. You will be more familiar with concepts after learning vectors. Look at the given shape which is a vector having magnitude and direction. We can change the position of the vector however, we should be careful not to change the direction and magnitude of it. In next subject we will learn how to add and subtract vectors. Moreover, we will learn how to find the X and Y components of a given vector using a little bit trigonometry.
