Angular Velocity Calculator
Angular Velocity
Angular velocity is one of the most important concepts in physics, especially when dealing with rotational motion. It describes how fast an object rotates around a fixed axis. Whether you are a student, engineer, or physics enthusiast, understanding angular velocity is essential for solving many real-world problems.
In this guide, you will learn what angular velocity is, its formulas, types, real-life applications, and how to use an Angular Velocity Calculator to simplify calculations.
What is Angular Velocity?
Angular velocity refers to the rate at which an object changes its angular position with respect to time. In simple words, it measures how quickly an object rotates.
It is represented by the symbol ω (omega) and is typically measured in radians per second (rad/s).
Angular Velocity Formula
The two most common formulas are:
1. ω = θ / t
Where θ is the angular displacement in radians and t is time in seconds.
2. ω = 2π / T
Where T is the time period of one complete rotation.
Angular Velocity Formula & Diagram
ω = θ / t
Angular velocity equals angle divided by time
ω = 2π / T
Angular velocity using time period
v = rω

Units of Angular Velocity
The standard unit is radians per second (rad/s). Other units include degrees per second and revolutions per minute (RPM).
Types of Angular Velocity
Uniform Angular Velocity
Occurs when an object rotates at a constant speed.
Non-Uniform Angular Velocity
Occurs when the rotational speed changes over time.
Real-Life Examples
Angular velocity is everywhere in daily life:
- Rotation of car wheels
- Spinning ceiling fans
- Earth’s rotation
- Ferris wheels
