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.

Why is the law of inertia for rotating system in terms of angular momentum?
The law of inertia for rotating systems is described in terms of angular momentum because angular momentum is conserved in the absence of external torques, similar to how linear momentum is conserved in the absence of external forces according to Newton's first law. This conservation of angular momentum provides a useful way to analyze and understand the motion of rotating systems.
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.
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.
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?
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 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.

Angular momentum about the center of the planet is conserved?
Angular momentum is conserved when there is no external torque acting on a system. For a planet, the net torque acting on it is negligible, so its angular momentum about its center will be conserved unless acted upon by an external force. This conservation principle is a consequence of the rotational symmetry of the system.
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.
Is angular momentum conserved in the system?
Yes, angular momentum is conserved in the system.
What is an angular momentum?
Angular momentum is a measure of an object's rotational motion, calculated as the product of its moment of inertia and angular velocity. It is a vector quantity, meaning it has both magnitude and direction, and is conserved in the absence of external torques. Angular momentum plays a crucial role in understanding the behavior of rotating objects, such as planets orbiting the sun or a spinning top.
Is the angular momentum about the center of the planet conserved?
Yes, the angular momentum about the center of the planet is conserved.
Why is angular momentum conserved during a collision, while linear momentum is not conserved?
Angular momentum is conserved during a collision because the total amount of rotational motion remains constant due to the principle of conservation of angular momentum. This is because there are no external torques acting on the system during the collision. On the other hand, linear momentum is not conserved during a collision because external forces, such as friction or air resistance, can act on the objects involved, causing a change in their linear motion.
