# Difference between Vectors and Scalars

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 a few scalar quantity examples. Force, velocity, and acceleration are some vector quantity examples.

Now, we learn in detail about scalar and vector quantities.

Scalars | vectors |

Physical quantities have magnitude only but no direction. | Physical quantities have 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. |
