🔶03 - Components of a Vector (3D) | Unit Vectors Position Vectors Solved Examples

In todays video, we shall discuss the concept of unit vectors and position vectors as well as the components of a vector. How to find the vector joining two points in a plane. Magnitude of a vector.

A Scalar is a quantity that is completely defined by a single value(magnitude) with an appropriate unit. Eg, mass, length, speed.
A vector is a quantity that is completely defined when we know not only its magnitude but also the direction in which it operates.
Eg. force, acceleration, velocity.

We shall also discuss
1. Line segment
2. Directed line segment
3. how to find the magnitude of a vector
4. Types of Vectors
