The difference between speed and velocity are given below:

SN |
Speed |
Velocity |

1. | It is the rate of change of distance. | It is the rate of change of displacement. |

2. | speed is always positive. | velocity may be positive, negative, or zero. |

3. | It is a scalar quantity. | Velocity is a vector quantity. |

The similarity between speed and velocity is their unit. Speed and velocity have the same uint, **m/s**
