The term vectors have been commonly heard in mathematics and physics and one might be perplexed of why this concept has so much relevance and importance in scientific studies. Any quantity that is meant to describe motion or any other measure in the physical world will certainly require the use of vectors. Simply a vector can be defined as a scalar quantity that is complete only when described by the magnitude of the quantity. Or in other words a vector is a quantity that has a direction along with its magnitude (Bbc.co.uk, 45-49). The magnitude is the scalar quantity that is supported through the direction to make it a vector quantity. In all other aspects vectors are similar to scalars like in arithmetic operations of addition, subtraction and others. This research paper is meant to research vectors in detail and its application to our daily activities.

BASICS OF VECTORS

This section of the research shall be devoted to understanding some of the fundamental concepts of vectors and its applications so that motion and its forces in two dimensions may be descriptively understood.

A vector is an element of the real coordinate space or the vector space in physics. Velocity, force, acceleration and displacement are typical and the most common examples of vectors. These quantities describe motion in a much more unique way than a normal scalar quantity. For instance if you are required to find an object and you are told that it is located inside the room, the information may not be sufficient for you to accomplish the task, but instead if you are told that the object is located 100 metres west at an angle of 45 degrees from the entrance of the room, the vector has been completely described in terms of displacement (Chana, 29-47). That is both the magnitude and direction have been specified. Unless it is not described so the vector quantity is incomplete.
