Scalar Quantity

                              Vector Quantity

scalar is a quantity with only magnitude and no direction. 

A vector is a quantity that has both magnitude and direction. 

Regardless of how they are used, they are always one-dimensional. 

In terms of application, it might be one, two, or three dimensional. 

Only the magnitude of a scalar quantity can vary. 

The magnitude of a vector quantity can change, as can the direction in which it is applied. 

The standard algebraic rules apply to scalars.

A scalar quantity can divide another scalar quantity fully. 

There is no way for a vector quantity to divide another vector quantity. 

A scalar amount will always be the result of two scalars. 

A scalar or a vector quantity can be the outcome of two vectors. 

Scalar quantities include mass, length, time, and so on. 

Velocity, acceleration, Polarization, and other vector quantities are examples.
