Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
angular momentum and angular velocity
Angular momentum is the product of the moment of inertia, and the angular velocity.
Newton meter seconds or Joule seconds.
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… Read More
No one knows WHAT it is, but its the "force" that causes all matter to attract all other matter. Angular momentum is a measure of how much work it would take to make something stop spinning.
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
when we churn and make out butter milk out of curd, here we apply angular momentum ceiling fan is another example of 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
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 mmtm is a cross product unlike linear momentum
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.
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."
if the angular speed of an object increase its angular momentum will also increase
Torque is the rate of change of angular momentum.
Rotating objects all have angular momentum.
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.)
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
Angular momentum is a vector quantity. Angular velocity, which is a vector quantity, is multiplied by inertia, which is a scalar quantity.
the equation of angular momentum is L=I*w (w=omega=angular velocity)
H = I ω H = angular momentum I = inertia w = inertial space
The angular momentum is a constant.
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
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
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.
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.
It isn't an object which can be found of itself, but objects possessing angular momentum are those which are turning.
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.
The angular momentum of a system is not conserved when a net external torque acts upon the system.
Earth's angular momentum remains the same throughout its 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.
A planet's angular momentum is constant, which is one way of stating Kepler's second law of planetary motion, the one about sweeping out equal areas. The angular momentum of the daily rotation is also constant.
Angular momentum of a rotating particle is defined as the moment of the linear momentum of the particle about that axis.It is perpendicular to the plane of rotation and parallel to the axis of rotation.
Is the direction of angular velocity same as that of angular momentum when agular velocity is decreasing?
Yes, suppose a body is rotating anti-clockwise, then its angular velocity and angular momentum, at any moment are along axis of rotation in upward direction. And when body is rotating clockwise, its angular velocity and angular momentum are along axis of rotation in downward direction. This is regardless of the fact whether angular velocity of the body is increasing or decreasing.
I believe that any particle in linear motion must also have some angular momentum because all particles have spin. In the case of a photon the spin, wavelength and angular momentum all vary with the relative linear velocity. So in my point of view time itself is the ratio between relative linear and angular momentum.
Angular momentum is the moment of momentum, a conserved vector quantity used to state the overall condition of a physical system.
The angular momentum quantum number, symbolized by l, indicates the shape of an orbital.
Anything that's spinning, rotating, tumbling, or traveling in a closed path around something else, has angular momentum.
The "intrinsic angular momentum" of particles is commonly called "spin". The spin of a photon is 1, in the units commonly used.
They both have momentum and their equations are similar.
No. An object has momentum only if it is in motion. . There are two kinds of momentum: linear momentum (or translational momentum), and angular momentum (or rotational momentum). . Linear momentum is a vector quantity and is calculated as mass x velocity (p = mv). Therefore, if an object's velocity is zero, then it has no linear momentum, but if an object is in motion, then it does have linear momentum. . VERY IMPORTANT… Read More
If a body is moving in a straight line then it would have angular momentum about any point which is not along its line of motion. The magnitude of the angular momentum would be its velocity times the perpendicular distance between the line of motion and the point.
When you are spinning there is a force called angular momentum that keeps you spinning and the angular momentum forms a ratio with the size of the object that is spinning so as you bring your arms inward, your size decreases increasing your angular momentum which spins you faster.
A rotating object's moment of inertia times its angular velocity.
Total angular momentum is always conserved - there is no way you can violate that law. So, the answer is yes.
What are the practical applications of Angular Speed Angular Displacement Angular Velocity and Angular Momentum?
These are used in lots of engineering problems related to rotation.
This is because of a law called conservation of angular momentum. If a star - which will usually have some rotation, and therefore some rotational momentum - collapses to a size of 20-30 km., angular momentum is conserved. Since the diameter decreases, it must spin faster. (Angular momentum is the product of a quantity called moment of inertia, which depends on the diameter of an object, and angular velocity.)
The angular momentum quantum number represents the quantum of angles a single moment can have. Usually two and a half. dayo
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
Only if there's no mass involved.
