Angular Momentum of a Single Particle
Angular momentum can be experienced by a single particle when the object is accelerating around a fixed position. For example, in case of the earth and the sun. Earth is revolving around the sun in its orbit, where the sun is fixed at its position.
Angular momentum, in that case is given by the formula,
where,
- is Angular Momentum
- r is Radius of Rotational Path
- is Linear Momentum of Object
Angular Momentum for Extended Object
Angular momentum can be experienced by a point object when the object is rotating about a fixed position. For example, in case of the earth rotating at its axis.
Angular Momentum, in that case is given by the formula,
where,
- is Angular Momentum
- I is Rotational Inertia
- is Angular Velocity of Object
Angular Momentum
Angular Momentum is a kinematic characteristic of a system with one or more point masses. Angular momentum is sometimes called Rotational Momentum or Moment of Momentum, which is the rotational equivalent of linear momentum. It is an important physical quantity as it is conserved for a closed system and follows the Law of Conservation of Angular Momentum. Angular Momentum is equal to the product of the moment of inertia (I), and the angular velocity (ω), of an object in rotational motion. Angular Momentum is a vector quantity. The SI unit of angular momentum is Kg.m2.s-1
