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.
What is torque when angular momentum is constant?
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.
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.
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.
What is the relation between torque and angular acceleration?
Torque is the rotational equivalent of force and is responsible for causing rotational motion. Angular acceleration is the rate at which an object's angular velocity changes. The relationship between torque and angular acceleration is defined by Newton's second law for rotation: torque is equal to the moment of inertia of an object multiplied by its angular acceleration.
Momentum is to force as angular momentum is to what?
Torque

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

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.
What must be exerted on an object to change the angular momentum?
A torque must be exerted on the object to change its angular momentum. Torque is the rotational equivalent of force and is required to cause an object to rotate or change its rate of rotation.
Is the total angular momentum conserved when there is a two car collision?
In a two-car collision, the total angular momentum is conserved only if no external torque is acting on the system. If there is no net external torque exerted on the cars during the collision, the total angular momentum before the collision will be equal to the total angular momentum after the collision.
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 name of the mechanism that produces the amount of torque?
An angular force would produce a large torque like angular momentum of a spinning wheel.
