Distinguish between speed and velocity.
| Speed | Velocity |
| Speed is the distance travelled by an object in a given interval of time. | Velocity is the displacement of an object in a given interval of time. |
| Speed = distance / time | Velocity = displacement / time |
| Speed is scalar quantity i.e. it has only magnitude. | Velocity is vector quantity i.e. it has both magnitude as well as direction. |
