Si unit of angular momentum is

Momentum is the product of mass and the velocity of the object. Any object moving with mass possesses momentum. The only difference in angular momentum is that it deals with rotating or spinning objects. So is it the rotational equivalent of linear 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 a vector quantity. The SI unit of angular momentum is Kg. Angular Momentum is defined as the property of objects in rotational motion which is determined by the product of their moment of inertia and angular velocity.

In physics , angular momentum sometimes called moment of momentum or rotational momentum is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity — the total angular momentum of a closed system remains constant. Angular momentum has both a direction and a magnitude, and both are conserved. Bicycles and motorcycles , flying discs , [1] rifled bullets , and gyroscopes owe their useful properties to conservation of angular momentum. Conservation of angular momentum is also why hurricanes [2] form spirals and neutron stars have high rotational rates. In general, conservation limits the possible motion of a system, but it does not uniquely determine it. Unlike linear momentum, angular momentum depends on where this origin is chosen, since the particle's position is measured from it. Angular momentum is an extensive quantity ; that is, the total angular momentum of any composite system is the sum of the angular momenta of its constituent parts. For a continuous rigid body or a fluid , the total angular momentum is the volume integral of angular momentum density angular momentum per unit volume in the limit as volume shrinks to zero over the entire body. Similar to conservation of linear momentum, where it is conserved if there is no external force, angular momentum is conserved if there is no external torque. Torque can be defined as the rate of change of angular momentum, analogous to force. The net external torque on any system is always equal to the total torque on the system; in other words, the sum of all internal torques of any system is always 0 this is the rotational analogue of Newton's third law of motion. Therefore, for a closed system where there is no net external torque , the total torque on the system must be 0, which means that the total angular momentum of the system is constant. The change in angular momentum for a particular interaction is called angular impulse , sometimes twirl. Thus, for example, the orbital angular momentum of the Earth with respect to the Sun is about 2.

The particles need not be individual masses, but can be elements of a continuous distribution, such as a solid body. This is principle of angular momentum conservation, which is similar to linear momentum conservation. When the object arrives at Bit receives an impulse directed toward point S.

Momentum is the product of mass and the velocity of the object. Any object moving with mass possesses momentum. The only difference in angular momentum is that it deals with rotating or spinning objects. So is it the rotational equivalent of linear momentum? If you try to get on a bicycle and balance without a kickstand, you will probably fall off. But once you start pedalling, these wheels pick up angular momentum. They are going to resist change, thereby making balancing gets easier.

Angular momentum AM is a physical quantity possessed by a body moving around a point. We can also define AM as the product of the linear momentum of the object and the perpendicular distance between the object and the axis of rotation. In the above image, we have an object of mass m revolving around the circle of radius r with speed v about an axis passing through center O. As we know the AM is the product of linear momentum and perpendicular distance from the axis of rotation so,. Also, m r 2 is the formula of the moment of inertia I , so we can write the equation of angular momentum as. This equation represents the mathematical form of the principle of conservation of AM. We know that the torque acting on a system is equal to the time rate of change of L of the system about that axis, i. The SI unit of angular momentum is kg m 2 s -1 , where kg is the kilogram, m is meter, and s is second.
