Lesson 1: Vectors introduction

Vector quantities have both a magnitude and a direction. In this example, we interpret a mathematical statement about two vector quantities in terms of the real-world quantities they represent. Created by Sal Khan.

• Does this ||a||=||b|| not mean its the same velocity? How is it different from a=b. Shouldn't the answer be A? • then how can we represent the option C in a mathematical manner?

before checking the answer, i assumed |vector A| = |vector B| might say same magnitude different directions (same as in the case of scalars), while ||vector A|| = ||vector B|| saying different magnitudes same direction

i googled it real quick but found nothing yet
