Angular momentum is an expression of an objects mass and rotational speed. Momentem is the velocity of an object times its mass, or how fast something is moving times how much it weighs. Therefore angular momentum is the objects mass times the angular velocity where angular velocity is how fast something is rotating expressed in terms like revolutions per minute or radians per second or degrees per second.

Angular momentum is a measure of an object's rotational motion, determined by the mass of the object, its angular velocity (rate of rotation), and the distribution of mass around its axis of rotation. It is a vector quantity, with both magnitude and direction, and is conserved in the absence of external torques.

The angular momentum of the earth is constant?
Yes, the angular momentum of the Earth is approximately constant. This is due to the fact that there are no external torques acting on the Earth as a whole. The Earth's rotation rate may vary slightly due to factors like tides, but its overall angular momentum remains fairly stable.
What is anguler momentum?
Angular momentum is a property of a rotating object that describes its tendency to keep rotating. It is calculated as the product of an object's moment of inertia and its angular velocity. Similar to linear momentum, angular momentum is conserved in the absence of external torques.
What quantities are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia (a measure of its mass distribution), its rotational velocity, and the object's shape. The formula for angular momentum is L = IĻ, where L is the angular momentum, I is the moment of inertia, and Ļ is the angular velocity.
How magnetic moment of electron is associated with angular momentum of electron?
magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.
In the angular momentum equasion what does the lower case omega mean?
The lower case omega (Ļ) represents angular velocity in the angular momentum equation. It is a measure of how quickly an object is rotating around an axis and is typically measured in radians per second.
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
What quanties are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia, its angular velocity, and the axis of rotation. The formula for angular momentum is given by L = I * Ļ, where L is the angular momentum, I is the moment of inertia, and Ļ is the angular velocity.
What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum. When a torque is applied to an object, it causes a change in the object's angular momentum. Conversely, an object with angular momentum will require a torque to change its rotational motion.
Which component of linear momentum does not contribute to angular momentum?
The linear momentum component that does not contribute to angular momentum is the component that is parallel to the axis of rotation. Only the perpendicular component of linear momentum contributes to angular momentum.
How do solve conservation of angular momentum?
To solve for conservation of angular momentum, set the initial angular momentum equal to the final angular momentum. This means that the total angular momentum before an event is equal to the total angular momentum after the event, assuming no external torques act on the system. This principle is commonly used in physics to analyze rotational motion.
How angular momentum of the earth remain constant?
As there is no external torque acting on it, its angular momentum remains constant. This is according to the law of conservation of angular momentum
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
No, the direction of angular velocity and angular momentum are not always the same. Angular momentum is defined as the cross product of the position vector and linear momentum, so the direction of angular momentum depends on both the direction of linear momentum and the position vector. Therefore, when angular velocity is decreasing, the direction of angular momentum may change depending on the specific conditions of the system.
Do all rotating objects have angular momentum?
Rotating objects all have angular momentum.
What is dimension of angular momentum?
The dimension of angular momentum is kg m^2/s.
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.
When the angular speed of an object increase its angular momentum may or may not increase?
if the angular speed of an object increase its angular momentum will also increase
Who invented angular momentum?
The concept of angular momentum was developed by Sir Isaac Newton in the 17th century. He observed that objects in motion can possess a type of rotational momentum, which is now known as angular momentum.
