Angular Momentum Calculator
What is Angular Momentum?
Angular momentum is a fundamental concept in physics that describes the rotational motion of an object. It is the rotational equivalent of linear momentum and plays a key role in understanding how objects move when they spin. Angular momentum depends on both the mass distribution of the object and its angular velocity.
It is represented by the symbol L and is measured in kg·m²/s. Angular momentum is widely used in mechanics, engineering, astronomy, and many real-world applications involving rotating systems.
The formula for angular momentum is:
L = I × ω
Where L is angular momentum, I is the moment of inertia, and ω is the angular velocity. The moment of inertia represents how mass is distributed relative to the axis of rotation, while angular velocity represents how fast the object is rotating.
This Angular Momentum Calculator helps you quickly calculate rotational momentum without complex manual calculations. It is ideal for students, engineers, and professionals working with rotational systems.
Why is Angular Momentum Important?
Angular momentum is conserved in isolated systems, meaning it remains constant unless acted upon by an external torque. This principle is known as the law of conservation of angular momentum and is widely observed in nature.
For example, a spinning ice skater rotates faster when pulling their arms inward. Similarly, planets maintain their motion around the sun due to angular momentum conservation. It is also used in designing turbines, gyroscopes, and rotating machinery.
