What is the formula for calculating the angular momentum expectation value in quantum mechanics?
The formula for calculating the angular momentum expectation value in quantum mechanics is L L, where L represents the angular momentum operator and is the wave function of the system.
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.
What is the formula for calculating the angular frequency () of a system in terms of the mass (m) and the spring constant (k)?
The formula for calculating the angular frequency () of a system in terms of the mass (m) and the spring constant (k) is (k/m).
Is angular momentum conserved in the system?
Yes, angular momentum is conserved in the system.
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when external torques are applied to the system. These torques can change the angular momentum by causing the system to rotate faster or slower or by changing the direction of its rotation.

When is angular momentum conserved in a physical system?
Angular momentum is conserved in a physical system when there are no external torques acting on the system.
Could the angular momentum of the closed system of mass change?
In a closed system where no external torque acts, the angular momentum remains constant (law of conservation of angular momentum). If external torques are present, the angular momentum of the system can change due to the torque causing rotation.
When is angular momentum conserved?
Angular momentum is conserved when there is no net external torque acting on a system. This principle is described by the law of conservation of angular momentum, stating that the total angular momentum of a system remains constant if there are no external influences causing a change.
How do solve conservation of angular momentum?
Usually you would use some fact you know about the physical system, and then write an equation that states that the total angular momentum "before" = the total angular momentum "after" some event.
How does the conservation of linear momentum relate to the conservation of angular momentum in a system?
The conservation of linear momentum and angular momentum are related in a system because they both involve the principle of conservation of momentum. Linear momentum is the product of an object's mass and velocity in a straight line, while angular momentum is the product of an object's moment of inertia and angular velocity around a point. In a closed system where no external forces act, the total linear momentum and angular momentum remain constant. This means that if one form of momentum changes, the other form may change to compensate, maintaining the overall conservation of momentum in the system.
When the rotational speed of a rotating system doubles its angular momentum?
When the rotational speed of a rotating system doubles, its angular momentum also doubles. This is because angular momentum is directly proportional to both the mass and the rotational speed of the system. Therefore, if the rotational speed doubles, the angular momentum will also double.
Is it true that if the total angular momentum of a system of particles is zero, then all the particles are at rest?
No, it is not necessarily true that if the total angular momentum of a system of particles is zero, then all the particles are at rest. The total angular momentum being zero means that the rotational motion of the system is balanced, but individual particles within the system can still have their own angular momentum and be in motion.
