What is the Difference Between Speed and Velocity?
| Difference | Speed | Velocity |
| Meaning | It is the rate at which a particular distance is covered by an object. |
Velocity refers to the the rate at which an object changes their position in a particular direction. |
| quantity | It is a scalar quantity as it comprises of magnitude only. |
Velocity is a vector quantity as it comprises of both magnitude and direction. |
| Indication | Speed indicates how fast an the object is moving. |
It indicates how fast the object is moving along with its position. |
| Value | Speed may never be zero or negative. |
Velocity may be zero, negative or positive. |
| SI Unit | One can measure speed in m/s. |
One can measure velocity in m/s. |
| Change of direction | If of the object changes the direction, it won’t matter because the count of average speed will continue. |
When the direction changes, there will be a change in the object’s velocity, thus, an object should follow one direction. |
| Interrelation | Speed can or cannot be equal to velocity. |
An object will possibly have different velocities but speed will be the same. |
| calculation | We calculate the speed as the difference traveled per unit of time. |
We calculate this as the displacement of a thing per unit of time. |
