How do planets orbiting the Sun and skaters doing a spin both conserve 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.

Which aspect of the nebula hypothesis accounts for the planets orbiting in the same direction and plane?
The conservation of angular momentum during the collapse of the primordial solar nebula is the aspect that accounts for the planets orbiting in the same direction and plane. As the nebula contracted and flattened into a spinning disk, this momentum caused the planets to form in a singular direction and plane, similar to the rotation of the original nebula.
What makes the planets to move around the sun?
The planets orbit the Sun because of gravity and their angular momentum, which ultimately derives from the energy of the Big Bang.
What keeps the planets and other solar system objects in orbit around the sun?
The force of gravity is what keeps planets and other objects in orbit around the sun, along with the angular momentum of the planets and objects. Without gravity, they would just fly away into space, and without angular momentum, they would just fall into the sun. But both of those together produce orbital motion.
Why planets is an example of rigid bodies?
The outer planets are not a very good example of rigid bodies because of their very thick atmospheres, but it is common to assume they are rigid for calculating the angular momentum.
Does angular momentum of a planet depend on its mass and distance from the sun?
Of course! The mass controls its speed, momentum, and how it tilts as its rotation around the sun continues. As a planet rotates on its axis, it will tilt at the sun, which is a big gravity machine. The earth is believe to be tilted because of collisions that are believed to have taken place billions of years ago. The earth collided with other proto planets in space, and became tilted. - pianodriver
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.
How does the conservation of angular momentum influence the expected spin of planets?
The conservation of angular momentum affects the expected spin of planets by causing them to rotate at a relatively constant speed as they orbit the sun. This means that planets are likely to have a consistent spin rate over time due to the conservation of angular momentum.
Where is angular momentum found?
Angular momentum is a property of rotating objects and is found in systems where there is rotational motion, such as spinning tops, planets orbiting stars, and moving particles with rotational motion. It is a quantity that describes the rotational inertia and velocity of an object around a specific axis.
Which aspect of the nebula hypothesis accounts for the planets orbiting in the same direction and plane?
The conservation of angular momentum during the collapse of the primordial solar nebula is the aspect that accounts for the planets orbiting in the same direction and plane. As the nebula contracted and flattened into a spinning disk, this momentum caused the planets to form in a singular direction and plane, similar to the rotation of the original nebula.
Most of the angular momentum of the solar system is found in the?
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.
Which aspect of the nebular hypothesis accounts for the planets orbiting in the same direction and plane?
The conservation of angular momentum within the collapsing solar nebula is the aspect of the nebular hypothesis that accounts for the planets orbiting in the same direction and plane. As the nebula collapsed, it began rotating in a single direction, resulting in a protoplanetary disk that formed planets orbiting in the same direction and plane.
In light of modern solar system theory why do the orbits of the planets all lie in nearly the same plane?
The orbits of the planets lie in nearly the same plane because they formed from a rotating disk of gas and dust around the young Sun, known as the solar nebula. As gravity caused material in the disk to clump together, it formed into the planets we see today, all orbiting in a flat plane due to the conservation of angular momentum.
What is the purpose of the planets rotation?
Your thinking is wrong. The rotation of a planet has not "been made" for a purpose. Planets rotate because of a law of nature called "the conservation of angular momentum". The dust cloud from which the a star and its planetary system forms had angular momentum (internal movements) and as gravity drew this matter together this momentum ends up as the spin of the star, its planets and the orbit of the planets round the star.
What caused planets to rotate?
Planets (and stars) were formed out of dust and gas. That had a rotation to it which does not go away (this is known as the Conservation of Angular Momentum).
What makes the planets to move around the sun?
The planets orbit the Sun because of gravity and their angular momentum, which ultimately derives from the energy of the Big Bang.
What idea is supported by the fact that the sun and planets rotate in the same direction on the same plane?
It's a demonstration of their angular momentum vectors being aligned in almost the same direction. Laplace added up all the vectors for the planets (the angular momentum vector is directed along the axis of rotation) and defined an invariable plane for the solar system, which is a plane that stays the same all the time. Total angular momentum is conserved so this plane will never change, even though momentum might be exchanged between the planets as their orbits change slightly.
Why are the planets rotating continuously?
There is no friction in space to stop them so they keep on spinning under what is called conservation of angular momentum.
