The online Circular Velocity Calculator tool helps to speed up the calculation and displays the result in a microsecond. The speed at which a body must travel to maintain an orbit near the edge of the earth's atmosphere. Circular Velocity is the name given to this speed.

Time Period

What is Circular Velocity?

In physics, circular motion is defined as an object moving around the circumference of a circle or rotating along its circular path. The object may be moving uniformly with a constant angular rate of rotation and speed, or it may be moving in a non-uniform manner with a variable rate of rotation. 

Objects moving in circles have a speed equal to the distance travelled divided by the travel time. As a result, the circular velocity of an object is defined as its speed in a circular motion. The formula for circular velocity is: v = 2πr/T


  • v = circular velocity
  • r = Radius of the circular orbit
  • T = Time period

How is Circular Velocity Calculated?

The following is the formula for calculating circular velocity: vc = 2πr / T

  • Where, r = radius of the circular orbit
  • T = time period.

If you know the angular velocity, you can calculate the circular velocity as follows: vc = ω r

  • Where, ω = angular velocity,
  • r = radius of the circular path

How Do I Use the Circular Velocity Calculator?

The following is how to use the circular velocity calculator:

  • Step 1: Fill in the unknown's radius, time period, and x in the appropriate input fields.
  • Step 2: To get the result, click the "Calculate the Unknown" button.
  • Step 3: Finally, the output field will show the value of x.

FAQs on Circular Velocity

1. What is Circular Velocity?

The velocity at which a body must travel to maintain an orbit near the edge of the earth's atmosphere. This velocity is called circular velocity.

2. What is the circular velocity formula?

The following is the formula for calculating circular velocity:

vc = 2πr / T

3. Is it possible for velocity to be negative?

A negative velocity object moves in the opposite direction. When an object slows down, its acceleration vector is in the opposite direction of its motion.

4. Is it possible for the average velocity to be zero?

The ratio of a body's total distance travelled to the total time interval required to cover that distance is known as average speed. Hence, the average velocity can be zero. The displacement of a car travelling in a circle is zero because the starting and ending points are the same.

5. What is the circular motion velocity?

The speed, mass, and radius are all constant in the simplest case. Consider a one-kilogram body moving in a one-metre radius circle at one-radian-per-second angular velocity. One metre per second is the speed. v2/r is the inward acceleration in metres per second.
