Velocity Calculator - Solve for Velocity, Distance, or Time
Calculate velocity from distance and time, or solve for distance or time given the other two variables.
Result
5.0000
v = d / t = 100 / 20 = 5.0000
How to Calculate Velocity
Velocity is the rate at which an object covers distance in a given direction, calculated by dividing distance traveled by the time taken. This calculator solves for any one of the three variables — velocity, distance, or time — as long as you provide the other two.
Example
A car covers 100 meters in 20 seconds. Its velocity is v = 100 / 20 = 5 m/s. If instead you knew the velocity (5 m/s) and time (20 s), you could solve for distance: d = 5 × 20 = 100 meters.
Common Use Cases
- Physics homework involving distance, time, and speed relationships.
- Estimating travel time given a known distance and expected average speed.
- Checking the average velocity of a moving object from a measured distance and elapsed time.
FAQs
What's the difference between speed and velocity?
Speed is a scalar quantity describing how fast something moves, while velocity is a vector that also includes direction. For straight-line calculations like this one, the numeric result is the same either way — only the interpretation differs.
Can I use any units for distance and time?
Yes — the calculator performs pure division and multiplication, so as long as you're consistent (e.g., meters and seconds, or miles and hours), the result will be in the matching unit (meters per second, miles per hour, and so on).
What if time is zero?
Velocity is undefined when time is zero, since you can't divide by zero. Enter a non-zero time value to get a valid result when solving for velocity or time.
