## What are the differences between scalars and vectors?

Scalars | vectors |

Physical quantities having magnitude only but no direction are called scalar quantities. | Physical quantities having magnitude and direction are called vector quantities. |

Scalar quantities are completely described by: 1:a number 2:a suitable unit |
vector quantities are completely described by: 1:a numbers 2:by a suitable unit 3:By certain direction |

Scalar quantities are added ,subtracted ,multiplied and divided by simple arithmetic rules. | Vector quantities cannot be added ,subtracted,multiplied and divide by simple arithmetical rules. |
