More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.
This statement is incorrect. Earth's angular momentum remains constant throughout its orbit around the Sun. Although Earth moves faster when it is closer to the Sun due to Kepler's second law of planetary motion, this is balanced by its greater distance from the Sun when it is farthest, resulting in a constant angular momentum.
Earth's angular momentum remains constant throughout its orbit around the Sun due to the conservation of angular momentum. The angular momentum at perihelion (closest point to the Sun) is the same as at any other point in its orbit.
Conservation of angular momentum.
Planets orbiting the Sun conserve angular momentum by maintaining a constant product of their mass, velocity, and distance from the Sun as they move in elliptical paths. Similarly, skaters conserve angular momentum by pulling their arms in during a spin, which increases their rotational speed to compensate for the decrease in their moment of inertia. In both cases, the total angular momentum remains constant unless acted upon by an external torque. This principle illustrates the fundamental conservation of angular momentum in different physical systems.
The highest value for orbital angular momentum is determined by the quantum number l, which can range from 0 to (n-1) where n is the principal quantum number. Therefore, the highest value for orbital angular momentum is (n-1)ħ, where ħ is the reduced Planck 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
The angular momentum is a 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.

A planet's angular momentum is constant, which is one way of stating Kepler's second law of planetary motion, the one about sweeping out equal areas. The angular momentum of the daily rotation is also constant.
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.
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.
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.
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.
Conservation of angular momentum.
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.
