What is difference between speed and velocity?
Differences Between Speed and Velocity
| S.No. | SPEED | VELOCITY |
|---|---|---|
| 1. | It is defined as the rate of change of distance. | It is defined as the rate of change of displacement. |
| 2. | It is a scalar quantity. | It is a vector quantity. |
| 3. | It can never be negative or zero. | It can be negative,zero or posituve. |
| 4. | Speed is velocity without direction. | Velocity is directed speed. |
| 5. | Speed may or may not be equal to velocity. | A body may possess different velocities but the same speed. |
| 6. | Speed never decreases with time. For a moving body, it is never zero. | Velocity can decrease with time. For a moving body , it can be zero. |
| 7. | Speed in SI is measured in ms-1 | Velocity in SI, is measured in ms-1 |
