Q. Difference between Speed and Velocity.
Top Answer
Solution:
Difference between Speed and Velocity.
| Speed | Velocity |
|---|---|
| 1. The rate at which an object covers distance. | 1. The rate at which an object changes its position in a specific direction. |
| 2. Speed is a scalar quantity (only has magnitude, no direction). | 2. Velocity is a vector quantity (has both magnitude and direction). |
| 3. Speed is always considered as positive quantity. | 3. Velocity can either be positive or negative or even zero. |
| 4. Its magnitude is either greater than or equal to that of velocity. | 4. Its magnitude is either equal to or less than that of speed. |
| 5. Calculated as Speed = Distance/Time | 5. Calculated as Velocity = Displacement/Time |
| 6. Example – A car moving at 60 kilometers per hour. | 6. A car moving at 60 kilometers per hour north. |
| 7. Remains constant even if the direction changes, as long as the rate of motion remains the same. | 7. Changes if either the speed or the direction of motion changes. |
