# Difference between scalar quantity and vector quantity in tabular form

The basic difference between scalar and vector quantity 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. |
