| 1. | Speed is the distance travelled by an object in unit time. | Velocity is the distance travlled by an object in unit time in a given direction. |
| 2. | Speed of a moving body can never be zero. | Velocity of a moving body will be zero is it returns to its original position. (i.e., when its displacement is zero.) |
| 3. | It is a scalar quantity. | It is a vector quantity. |
| 4. | Speed = `"Distance travalled"/"time taken"` | Velocity = `"Displacement"/"time taken"` |
