Calculated velocity
Velocity Calculator क्या है?
Velocity is a vector quantity that represents the rate at which an object changes its position. While "speed" only tells you how fast an object is moving, velocity tells you how fast and in what direction.
In standard physics problems, constant velocity is assumed, meaning the acceleration is zero. This calculator uses the basic kinematic equation v = d / t, allowing you to isolate any of the three variables if you know the other two.

Speed vs. Velocity
It is common to confuse speed and velocity, but in physics, they are distinct concepts:
A scalar quantity. It only has magnitude (e.g., 60 km/h). Direction does not matter.
A vector quantity. It has both magnitude and direction (e.g., 60 km/h North).
Common Unit Conversions
| From | To | Multiply By |
|---|---|---|
| km/h | m/s | 0.2778 |
| m/s | km/h | 3.6 |
| mph | m/s | 0.447 |

अक्सर पूछे जाने वाले प्रश्न
इस कैलकुलेटर के बारे में सामान्य प्रश्न
What is average velocity?
Average velocity is the total displacement divided by the total time taken. It doesn't account for speed changes during the trip—only where you started and where you ended.
Can velocity be negative?
Yes. In a coordinate system, velocity is negative if an object is moving in the opposite direction of the positive axis (e.g., moving left or down).
How does this differ from acceleration?
Velocity is the rate of change of position. Acceleration is the rate of change of velocity. If your velocity is constant, your acceleration is zero.
Why use meters and seconds?
Meters and seconds are the base units for distance and time in the SI (International System of Units), used by scientists and engineers worldwide.
