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
Who invented angular momentum?
The concept of angular momentum was developed by Sir Isaac Newton in the 17th century. He observed that objects in motion can possess a type of rotational momentum, which is now known as angular momentum.
In orbital motion the Angular Momentum of the system is?
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.
What is the orbital angular momentum formula and how is it used in physics?
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.
How do the moons stay in orbit around the sun?
The moons are around planets, planets are around the sun. But basically the orbit is a mix of forward momentum and the the pull towards the sun, this creats an angular movement. when the planet moves forward, this angular movement is now forward momentum and gravity is still pulling it towards the sun creating a angular movement and when added together this is roughly a circle that goes all around the sun.
Is the angular momentum about the center of the planet conserved?
Yes, the angular momentum about the center of the planet is conserved.
Angular momentum about the center of the planet is conserved?
Angular momentum is conserved when there is no external torque acting on a system. For a planet, the net torque acting on it is negligible, so its angular momentum about its center will be conserved unless acted upon by an external force. This conservation principle is a consequence of the rotational symmetry of the system.
Can a body in translatory motion have angular momentum?
No, a body in translatory motion does not have angular momentum as angular momentum is associated with rotational motion. Translatory motion involves motion along a straight line, while angular momentum involves rotation around an axis.
What keeps Venus up in space?
Angular momentum is what keeps the planet Venus up, in the sense of not falling into the sun. To be precise, it is the balance between the gravitational attraction of the sun, and the angular momentum of the planet, which keeps Venus in its orbit.
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
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
Which quantity remain constant in planetary motion as seen from sun?
The angular momentum of a planet remains constant in its motion around the sun. This is due to the conservation of angular momentum, which dictates that the product of the planet's mass, velocity, and distance from the sun remains the same as the planet orbits.
How do you calculate angular momentum in a rotating system?
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.
What quanties are needed to calculate angular momentum?
To calculate angular momentum, you need the object's moment of inertia, its angular velocity, and the axis of rotation. The formula for angular momentum is given by L = I * ω, where L is the angular momentum, I is the moment of inertia, and ω is the angular velocity.
How can linear momentum be converted to angular momentum?
Linear momentum can be converted to angular momentum through the principle of conservation of angular momentum. When an object with linear momentum moves in a curved path or rotates, its linear momentum can be transferred to create angular momentum. This conversion occurs when there is a change in the object's direction or speed of rotation.
What is the relation between torque and angular momentum?
Torque is the rate of change of angular momentum. When a torque is applied to an object, it causes a change in the object's angular momentum. Conversely, an object with angular momentum will require a torque to change its rotational motion.
Which component of linear momentum does not contribute to angular momentum?
Angular momentum is defined as the moment of linear momentum about an axis. So if the component of linear momentum is along the radius vector then its moment will be zero. So radial component will not contribute to angular momentum
