Using classical mechanics

Let Angular momentum (L), Linear momentum (P), Perpendicular distance to linear momentum from the relevant axis (r), and moment of inertia (I), velocity (v), mass (m), then

L= P * r

L= (mv)*r --------(1)

Also let, I= mr^2 ; (for a simple situation like particle rotate around an axis)

r= Sqrt (I/m) ; (Sqrt = Square root)

substituting into equation (1)

L = mv Sqrt(I/m)

L= v* Sqrt (I*m)

How do you calculate angular momentum in a rotating system?

Angular momentum in a rotating system is calculated by multiplying the moment of inertia of the object by its angular velocity. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.


How can one determine the angular momentum of a rotating object and what is the process for finding angular momentum?

To determine the angular momentum of a rotating object, you multiply the object's moment of inertia by its angular velocity. The moment of inertia is a measure of how mass is distributed around the axis of rotation, and the angular velocity is the rate at which the object is rotating. The formula for angular momentum is L I, where L is the angular momentum, I is the moment of inertia, and is the angular velocity.


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 * ω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.


Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?

Angular momentum about the axis of rotation is the moment of linear momentum about the axis. Linear momentum is mv ie product of mass and linear velocity. To get the moment of momentum we multiply mv by r, r the radius vector ie the distance right from the point to the momentum vector. So angular momentum = mv x r But we know v = rw, so angular momentum L = mr2 x w (w-angular velocity) mr2 is nothing but the moment of inertia of the moving body about the axis of rotation. Hence L = I w.


How angular momentum is equals to kgms?

Angular momentum is calculated as the product of a rotating object's moment of inertia (I) and its angular velocity (ω). The units of angular momentum are kg m^2/s, which is the same as the units for moment of inertia multiplied by angular velocity (kg m^2 * 1/s). This relationship is based on the principles of rotational motion and conservation of angular momentum.

What quantities are needed to calculate angular momentum?

"Rate of change" means that you divide something by time ("per unit time" or "per second"), so you would use the units of angular momentum, divided by seconds.I am not aware of any special name for this concept.


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 is ment by angular momentum and angular velocity?

Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.


When a spinning skater pulls in her arms to turn fasterher angular momentum?

When a spinning skater pulls in her arms to turn faster, her angular momentum is conserved. Angular momentum is the product of an object's moment of inertia and its angular velocity. By pulling her arms in, the skater decreases her moment of inertia, causing her angular velocity to increase in order to maintain a constant angular momentum. This is similar to the principle of conservation of angular momentum seen in other rotating systems.


Is angular momentum always parallel to angular acceleration?

momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel


How does mass affect angular momentum?

Short answer: Angular momentum is proportional to mass. If you double the mass of an object, you double its angular momentum.Long Answer:Angular Momentum is a characteristic of rotating bodies that is basically analogue to linear momentum for bodies moving in a straight line.It has a more complex definition. Relative to an origin, one obtains the position of the object, the vector r and the momentum of the object, the vector p, and then the angular momentum is the vector cross product, L.L=r X p.Since linear momentum, p=mv, is proportional to mass, so is angular momentum.Sometimes we speak of the angular momentum about the center of mass of an object, in which case one must add all of the bits of angular momentum for all the bits of mass at all the positions in the object. That is easiest using calculus.It should also be said that the moment of inertia, I, is proportional to mass and another way to express angular momentum is the moment of inertia times the angular velocity.


Why does a skater angular velocity increase when putting their arms in?

the equation for rotational kinetic energy (KE) is:.KE = 0.5 * I * ((rad / sec)^2), where I is the mass moment of inertia..so if the kinetic energy remains constant, the only thing that can alter the rotation rate (rad / sec), is I, the mass moment of inertia
