# 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.

### How angular momentum of the earth remain 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

### What is rotational momentum of the moon about earth?

The angular momentum of the Moon increases with the square root of the distance. It is the angular momentum of the earth-moon system that remains constant.

### If a particle moves in circle with constant speed its angular momentum about the center of circle?

The angular momentum is a constant.

### Why does earth rotate constantly?

Actually it doesn't - but the changes are quite small. There is a physical law called Conservation of Angular Momentum - the total angular momentum (informally, we might say the "amount of rotation") can't increase or decrease in a closed system. If the distribution of masses on Earth changes, Earth's angular velocity can change - but any redistribution of masses is rather small-scale, compared to the size of the Earth. On the other hand, Earth… Read More

The angular momentum quantum number indicates the shape of the orbital. It is used to describe the electron atom's angular momentum and is written as "I."

### What is ment by angular momentum and angular velocity?

Angular velocity means how fast something rotates. The exact definition of angular momentum is a bit more complicated, but it is the rotational equivalent of linear momentum. It is the product of moment of inertia and angular speed.

### Why does the earth keep spinning?

Basically, the Law of Conservation of Angular Momentum. Any spinning object has a tendency to continue spinning. To slow down Earth, a force would be required to slow it down - and the angular momentum would have to be transferred somewhere else.

### If something shrinks in size but not in mass what happens to its angular momentum?

Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster. Angular momentum is maintained in such a case - and in fact in all cases, unless angular momentum is transferred to, or from, another body. This means it must rotate faster. Angular momentum is maintained in such a case - and in fact in… Read More

### Is angular momentum a vector quantity?

Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.

### In the angular momentum equasion what does the lower case omega mean?

the equation of angular momentum is L=I*w (w=omega=angular velocity)

### Which force acts for the revolution of the earth in its own axis?

no force, just angular momentum which is conserved.

### What equations link angular and linear momentum If you exert a force on a free floating body it will have angular and linear momentum In what proportions and how are they linked?

angular momentum = linear momentum (of object) x perpendicular distance (from origin to the object) where x stands for cross product. angular momentum = mv x r (perpendicular dist.)

### How do you change an objects momentum?

Momentum is of two kind. One is linear momentum and the other is angular momentum. Linear momentum is defined as the product of the mass and the velocity. Hence a vector quantity. To change the momentum of a given body with its mass constant, its velocity is to be changed. Velocity change could be made by changing its magnitude or direction or both. Angular momentum is the product of moment of inertial and the angular… Read More

### What is the formula for angular momentum?

H = I ω H = angular momentum I = inertia w = inertial space

### How does mass affect angular momentum?

Short answer: Angular momentum is proportional to mass. If you double the mass of an object, you double its angular momentum. Long Answer: Angular Momentum is a characteristic of rotating bodies that is basically analogue to linear momentum for bodies moving in a straight line. It has a more complex definition. Relative to an origin, one obtains the position of the object, the vector r and the momentum of the object, the vector p, and… Read More

### Where is angular momentum found?

It isn't an object which can be found of itself, but objects possessing angular momentum are those which are turning.

### The earths angular momentum when it is nearest to the sun is greater then when it is farthest from the sun?

The earths angular momentum would be the same.

### Is angular momentum always parallel to angular acceleration?

momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

### 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.

### How the angular momentum of earth is constant explain how?

T=I A(alpha) , T = I * DALTA W (OMEGA)/DALTA T , SINCE I*W (OMEGA) = DALTA L(ANGLUAR MOMENTUM ) So, T = DALTA L / DALTA T , Thus , As rate of change of anguar momentum is equal to torque . so we know that earth revolves around sun while torque acting on it is zero . so here we may conclude that T=DALTA L / DALTA T , T= O => np… Read More

### How is the spin of an elementary particle measured?

Spin is either up or down and in positive half integer multiples of an angular momentum quantum constant: h/(2∏), where h is Planck's constant.

### Why is angular momentum of a body is equal to the product of its moment of inertia and angular velocity?

Angular momentum about the axis of rotation is the moment of linear momentum about the axis. Linear momentum is mv ie product of mass and linear velocity. To get the moment of momentum we multiply mv by r, r the radius vector ie the distance right from the point to the momentum vector. So angular momentum = mv x r But we know v = rw, so angular momentum L = mr2 x w (w-angular… Read More

Earth's angular momentum remains the same throughout its orbit around the sun.

### Why does Earth rotate on its axis?

Conservation of angular momentum. The matter that formed Earth and the other members of the solar system was in a swirling disk of dust. The angular momentum of that mass has been conserved according to the laws of motion and so the planets rotate around their axes as well as are in orbit around the Sun.

magnetic moment of a particle is due to its motion around some other orbits or about its own orbit i.e due to its orbital angular momentum or its spin angular momentum.

### Is the moon held in orbit by the force of gravity?

Gravity attracts the moon toward the Earth, and the moon's angular momentum pulls in the opposite direction. With gravity alone, the moon would crash into the Earth, and with angular momentum alone the moon would fly away into outer space. But in combination, these produce an orbit.

### The angular momentum quantum number 1 indicates the?

The angular momentum quantum number, symbolized by l, indicates the shape of an orbital.

### What is angular mementum?
