Difference between speed and velocity .
| Speed | velocity |
| 1 . Speed of a body is the distance travelled by it per unit time | 1. Velocity of a body is the distance travelled by it per unit time in a given direction |
| 2 . In speed , the direction of motion of the body is not specified | 2. In velocity , the direction of motion of the body is specified |
| 3. Speed has only magnitude , so speed is a scalar quantity | 3 . Velocity has both , magnitude as well as direction , so velocity is a vector quantity |
