Physics Velocity: Distance Over Time
Average velocity is the simplest motion formula: how far, divided by how long. This calculator also converts it to km/h.
What is the Physics Velocity Calculator?
Enter distance in metres and time in seconds. Average velocity is distance divided by time, in metres per second. All physics tools here use standard textbook formulas, labelled as such.
How to use it
- Enter the values in the labelled units.
- Click Calculate Velocity.
- Read the result and its formula.
Worked example
Travelling 100 m in 20 seconds is 5 m/s, or 18 km/h.
What velocity is 100 m in 20 seconds?
5 metres per second, or 18 km/h.
Frequently asked questions
What units should I use?
Use the units on the labels (kg, m, s, N, J, W) so the formula's result comes out in standard units.
Is this exact?
The formula is standard textbook physics; real measurements carry their own errors, but the arithmetic is exact.
