Circular running linear speed calculator

I want to calculate
Radius (r) = m
Time period (T) = s
Circular velocity (v) = m/s
 

A Circular Running Linear Speed Calculator determines the linear speed of an object moving along a circular path. Linear speed is different from angular speed—it measures how fast an object moves along the circumference rather than how fast it rotates.

Why use it?

  • To calculate the actual speed of a runner on a circular track.
  • To determine the speed of rotating objects like wheels or gears.
  • Useful in physics, engineering, and sports science.

How does it work?

It uses the formula:

v = r × ω

Where:

  • v = linear speed (m/s)
  • r = radius of the circular path (m)
  • ω = angular speed (rad/s)

If you know the time taken for one full revolution (T), you can use:

ω = 2π​ / T

When to use it?

  • When analyzing motion on curved tracks.
  • In mechanical systems involving rotation.
  • In athletic training for track performance.
