Q. What are vectors ?

Ans. A vector is an object that has both a magnitude and a direction. Geometrically, 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.
