Scalars and Vectors
Vectors: A vector is a leaning quantity; it has magnitude and the direction. Velocity, force and displacement these are the examples for vectors. Vectors are represented using the arrow above the letters like Vec (a). Normally a vector needs two main things which are magnitude and direction.
Scalars: Scalars have no direction associated to them, it has only magnitude. Time, temperature, mass and energy these are the example for scalars. It has only magnitude there is no direction in this. Vectors and Scalars are represented using number lines.
