When angular momentum is constant, torque is zero. This means that there is no net external force causing the object to rotate or change its rotational motion. The law of conservation of angular momentum states that if no external torque is acting on a system, the total angular momentum of the system remains constant.
What else can I help you with?
Why can angular momentum not be conserved if an external torque is applied to a rotating object?
When an external torque is applied to a rotating object, the total angular momentum of the system is no longer constant because the external torque changes the rotational motion of the object by adding or subtracting angular momentum. This violates the principle of conservation of angular momentum, which states that the total angular momentum of a system remains constant if no external torques are acting on it.
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.
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.
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.
What is the angular momentum of the ice skater spinning with her arms out and not being acted upon by an external torque?
The angular momentum of the ice skater spinning with her arms out and not being acted upon by an external torque remains constant.
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

If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
In orbital motion the Angular Momentum of the system is?
In orbital motion, the angular momentum of the system is constant if there is no external torque acting on the system. This is a result of the conservation of angular momentum, where the product of the rotating body's moment of inertia and angular velocity remains constant unless acted upon by an external torque.

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.

Momentum is to force as angular momentum is to what?
Torque
If a particle moves in circle with constant speed its angular momentum about the center of circle?
The angular momentum is a constant.
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
How is torque related to angular momentum and what is the significance of this relationship?
Torque is the force that causes an object to rotate around an axis. Angular momentum is the measure of an object's rotational motion. The relationship between torque and angular momentum is that torque applied to an object will change its angular momentum. This relationship is significant because it explains how forces can affect the rotation of objects, such as in the case of spinning wheels or rotating machinery.
