Answer
| Speed | Velocity |
|---|---|
| The distance travelled per second by a moving object is called its speed. | The distance travelled per second by a moving object in a particular direction is called its velocity. |
| It is a scalar quantity. The speed does not tell us the direction of motion. | It is a vector quantity. The velocity tells us the speed as well as the direction of motion. |
| The speed is always positive since direction is not taken into consideration. | The velocity can be positive or negative depending upon the direction of motion. |
| After one round in a circular path, the average speed is not zero. | After completing each round in a circular path, the average velocity is zero. |
