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 change in DALTA L i.e DALTA L = CONSTANT . so now we may conclude that when earth revolves aroung sun angkuar momentum is constant.
What else can I help you with?
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 the force or mechanism that causes the Earth to spin on its axis?
The force that causes the Earth to spin on its axis is called angular momentum. This is a property of rotating objects that keeps them spinning unless acted upon by an external force. In the case of the Earth, its initial rotation was likely caused by the conservation of angular momentum during its formation billions of years ago.
What causes the Earth to spin on its axis?
Oh, what a delightful question. The Earth spins on its axis all thanks to an event long, long ago when our planet formed out of cosmic dust and other celestial materials coming together. Just like a gentle spiral of paint on our canvas, the Earth keeps turning, dancing through space with grace and purpose.
Why does the world pivot on its axis?
The world spins around because of the way the solar system was formed as a spinning cloud of matter. This then it began to collapse in on itself as it did this the heat at the centre became so great that the sun ignited and pushed out all the matter which then formed the planets, still spinning because of the energy from the explosion as the sun ignited.Supplement 2 As far as the planets are concerned, they would have had some net rotational momentum, the residual of all the components that made the planet.This rotational energy cannot be destroyed - it however might be cancelled out by opposite-spin material.BUT back to the question. The Earth carries the residual net spin from its assembly from space debris.Answer:The rotation comes about from the conservation of angular momentum. The formula for angular momentum is:L=mwr2m is the mass,w is the angular velocity in radians per second, andr is the radius of the circular motion.Due to conservation of angular momentum, as the radius of the orbit decreases, then its angular velocity must increase (as the mass is constant). As a consequence the parts of the planet closer to the primary (the Sun) must rotate faster than the parts furthest from the Sun. This causes the spin.This all relates to the fact that planetary and stellar systems are born from the collapse of dense interstellar clouds. As the clouds collapse even a small rotation is magnified by the contraction. If the clouds were not rotating (matter fell straight to the center of the system) there would be no planets.
What holds up the moon?
The moon is held in orbit around Earth by gravity. The gravitational force between the Earth and the moon keeps it from drifting off into space.
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
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.
The earths angular momentum when it is nearest to the sun is greater then when it is farthest from the sun?
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.
What is Earth's angular momentum when it is at perihelion in its orbit?
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.
Why the earth was revolving?
Conservation of angular momentum.
What makes the earth to rotate around the orbit?
The Earth condensed out of a rotating Solar Nebula, inheriting its angular momentum for the condensing cloud. The conservation of angular momentum allows the Earth to maintain its orbit.
What is the Law of Change that states earth movements at a constant rate?
Do you mean what Law of Conservation keeps the Earth spinning at the same rate? If so, that's the Conservation of Angular Momentum.
What is the significance of the angular momentum of Earth about its axis in relation to its rotational motion and stability?
The angular momentum of Earth about its axis is important for its rotational motion and stability. It helps to maintain the planet's balance and keeps it spinning consistently. Changes in angular momentum can affect the Earth's rotation speed and axis tilt, which can impact climate and seasons.
What is the significance of the angular momentum of Earth around the Sun in relation to its orbit and rotational motion?
The angular momentum of Earth around the Sun is important because it helps to maintain the stability of Earth's orbit and rotational motion. Angular momentum is a measure of how fast an object is spinning and how spread out its mass is. In the case of Earth, its angular momentum keeps it in a stable orbit around the Sun and helps to regulate its rotation, ensuring that it maintains a consistent speed and direction as it moves through space.
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 rotates slower and slower over time - angular momentum is transferred to the Moon in this case.
What does the earth spins on?
the earth spins on an axis, which is carried over by conservation of angular momentum when the earth was created
Which force acts for the revolution of the earth in its own axis?
no force, just angular momentum which is conserved.
