Velocity Calculator

Calculate the velocity of an object. Enter the objects initial position, final position, and time elapsed to determine the velocity.

Velocity is often described as the rate of change in position of an object or system. Velocity is a vector quantity which means that it has a magnitude and a direction. For example, an object could be speeding along at 30m/s in the x direction and 0m/s in the Y direction. Speed is the magnitude, and the motion is the direction. The formula for determining velocity can look something like this.

Velocity = (Position 1 – Position 2)/ Time (s)

Where position 1 and 2 are described as a coordinate system in the x,y, and z plane.


Acceleration is the derivative of velocity. If you think about this, it means that acceleration is the rate of change of velocity. Or in other words, the rate of change of the rate of change.

Velocity, just like acceleration, is all part of a of Newton’s second law of motion, which is derived from the formula for force, F=ma.
