About the Velocity Calculator

Velocity is a vector quantity that describes the rate of change of an object's position. Unlike speed, which is a scalar quantity containing only magnitude, velocity specifies both the speed of the object and its direction of motion.

Mathematical Formula & Logic

The formula for average velocity is: v = d / t Where: - v = Velocity in meters per second (m/s) or km/h, mph - d = Displacement (change in position) in meters (m) - t = Time duration in seconds (s)

Step-by-Step Example

A runner travels a displacement of 400 meters east in 80 seconds. Calculate the velocity: v = d / t v = 400 m / 80 s = 5 m/s East.

Frequently Asked Questions

Speed is a scalar quantity representing how fast an object is moving. Velocity is a vector quantity representing both how fast and in what direction the object is moving.
Yes. An object moving in a circle at a constant speed (like a car going around a roundabout) is constantly changing direction, which means its velocity is constantly changing.
Instantaneous velocity is the velocity of an object at a specific instant of time. It is calculated in calculus as the derivative of displacement with respect to time (ds/dt).
