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.
The majority of the angular momentum of the solar system is found within the orbital motion of the planets around the Sun. This motion results in the spinning of the planets on their axes and the overall rotation of the solar system as a whole.
The orbital angular momentum formula is L = r x p, where L is the angular momentum, r is the position vector, and p is the momentum vector. In physics, this formula is used to describe the rotational motion of an object around a fixed point. It helps in understanding the conservation of angular momentum and the behavior of rotating systems, such as planets orbiting the sun or electrons moving around an atomic nucleus.
They don't rotate in the same direction. But most of the rotation comes about from the conservation of angular momentum. Angular momentum is given by L=m*w*r2 where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion. Due to conservation of angular momentum, if the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). Hope I answered your question...

Well actually, not all of the planets move in a perfect circle. Uranus's orbital path is effected by the gravitational pull from Neptune. But the planets move in a orbital path because of the gravitational pull from the sun. Since the sun is circular, they move around the sun, so that's why they move in a orbital path.
Almost certainly. As the dust and gas fall into the nebula under its gravity, each atom will impart SOME sort of sideways momentum, and the total of all that is almost certainly not zero; there will be some angular momentum.

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.
The time derivative of angular momentum is equal to the torque acting on a rotating system. This means that changes in angular momentum over time are directly related to the rotational motion of the system and the external forces causing it to rotate.
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.

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.
Yes, angular momentum is conserved in the system.
Conservation of angular momentum states that the total angular momentum of a system remains constant in the absence of external torques. This principle is important in understanding the behavior of rotating objects in physics and plays a key role in areas such as orbital motion of planets and stars, gyroscopic stabilization, and the motion of spinning objects. It helps to predict the rotational motion of objects and systems based on initial conditions without the need to consider all the complex forces acting on them.
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.
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.
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.
Angular momentum is conserved in a physical system when there are no external torques acting on the system.
