Concept Of Vector
To understand the concepts of physics clearly, it is important to know the difference
between scalars and vectors first. But is it enough to know that scalars have magnitude
alone, while vectors have both magnitude and direction? How do we represent a vector?
What are its properties? What are null vectors and unit vectors? What are the basic
laws of vector algebra, and where do we apply them? The video lecture “Concept
of Vector” answers some of these questions, and more.
