Most of the angular momentum of the solar system is found in the?
orbits of the planets.
Which of the following describes orbital motion of these bodies in your solar system?
kinetic energy
Why do planets follow circular orbital paths?
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.
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 all lie in nearly the same plane for preservation of angular momentum.
Why do planets turn?
Stars and planets form in the collapse of huge clouds of interstellar gas and dust. The material in these clouds is in constant motion, and the clouds themselves are in motion, orbiting in the aggregate gravity of the galaxy. As a result of this movement, the cloud will most likely have some slight rotation as seen from a point near its center. This rotation can be described as angular momentum, a conserved measure of its motion that cannot change. Conservation of angular momentum explains why an ice skater spins more rapidly as she pulls her arms in. As her arms come closer to her axis of rotation, her speed increases and her angular momentum remains the same. Similarly, her rotation slows when she extends her arms at the conclusion of the spin.In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The sun itself rotates slowly, only once a month. The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus. These differences are believed to stem from collisions that occurred late in the planets' formation. (A similar collision is believed to have led to the formation of our moon.)Planets rotates beacos the sun tells them to
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when a net external torque acts upon the system.
What is an angular momentum?
An angular momentum is the vector product which describes the rotary inertia of a system around its axis and is conserved in a closed system.
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.
The angular momentum of the earth is constant?
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.
What is angular mementum?
Angular momentum is the moment of momentum, a conserved vector quantity used to state the overall condition of a physical system.
How do solve conservation of angular momentum?
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.
Most of the angular momentum of the solar system is found in the?
orbits of the planets.
What is the law of inertia for rotating systems in terms of angular momentum?
An object or system of objects will maintain its angular momentum unless acted upon by an external net torque.
When the rotational speed of a rotating system doubles its angular momentum?
Gets doubled
What are the allowed total angular momentum quantum numbers of a composite system in which j1 5 and j2 3?
Using the commutation relation will help us compute the allowed total angular momentum quantum numbers of a composite system.
Why do toilets swirl?
Toilet water swirls due to a law of motion called "Angular Momentum". This is one of the laws of planetary motion discovered by Keppler. It basically describes the natural movement of matter whether it be water in a toilet bowl, planets around a sun or galaxies around a black hole. This natural movement is of a circular nature.Of course in a toilet bowl often times the water shoots out at an angle upon flushing so that a circular motion is created on purpose. But a more natural example of this is the water that goes down the drain in a bath tub. Again we see the same motion as a galaxy around a central mass in the center. This is theorized to either be a black hole or simply a globular cluster of stars forming a gravitic mass at the center of each galaxy to which other stars are pulled into via the strong gravitational pull of this gravitic mass or black hole.For a much more detailed and specific explanation of angular momentum, keep reading and visit the Wiki link below.In physics, the angular momentum of a particle about an origin is a vector quantity equal to the mass of the particle multiplied by the cross product of the position vector of the particle with its velocity vector.[1] The angular momentum of a system of particles is the sum of that of the particles within it.[2] Angular momentum is an important concept in both physics and engineering, with numerous applications. Angular momentum is important in physics because it is a conserved quantity: a system's angular momentum stays constant unless an external torque acts on it. Rotational symmetry of space is related to the conservation of angular momentum as an example of Noether's theorem. The conservation of angular momentum explains many phenomena in nature. http://en.wikipedia.org/wiki/Angular_momentum
What are the different states of quantum state?
There are 4 quantum numbers that specify the quantum system. n is the energy level, l is the angular momentum, ml is the projection of angular momentum, ms is the spin projection.
