# Vectors and Scalars Quantities The basic difference between vectors and scalars is that scalar quantity is described completely by its magnitude only while vector quantity is described by magnitude and direction. Speed, energy, power are few scalar quantity examples. Force, velocity, and acceleration are some vector quantity examples.
Now, we learn in detail about scalar and vector quantities.

## Scalar quantity Vs Vector quantity

 Scalars vectors Physical quantities having magnitude only but no direction . Physical quantities having magnitude and direction . These quantities are completely described by: 1:a number 2:a suitable unit These quantities are completely described by: 1:a numbers 2:by a suitable unit 3:By certain direction These quantities are added, subtracted, multiplied, and divided by simple arithmetic rules. These quantities cannot be added, subtracted, multiplied, and divide by simple arithmetical rules.
