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.
When there is no external force acting on a body , which physical quantity is conserved?
Angular Momentum. The conserved quantity we are investigating is called angular momentum. The symbol for angular momentum is the letter L. Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
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 can you prove angular momentum is quantized?
Angular momentum is one of three distiguishing properties of motion. It being quatized means that it cannot continuously vary, it varies only in quantum leaps between two set values.

If the torque of the rotational motion be zero then the constant quantity will be?
angular momentum
What is meant by quantization in physics?
When a quantity is "quantized," it means that the quantity exists in discrete indivisible units. For example, the magnitude of electric charge is quantized, and the quantum of electric charge is the charge of the electron e. There is no known free particle with a charge of 1/2 e or 9.1254e, only particles with charges of 1e, 2e, 5e, 99e, 423425e, etc.There are numerous other quantities that can be quantized including angular momentum, energy, and even electrical conductance.
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
Angular momentum is a measure of?
angular momentum is the measure of angular motion in a body.
What does Ħ mean?
A modified form of Planck's constant called h-bar (ℏ), or the reduced Planck's constant, in which ℏ equals h divided by 2π, is the quantization of angular momentum. For example, the angular momentum of an electron bound to an atomic nucleus is quantized and can only be a multiple of h-bar.
Do all objects have a momentum?
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 NOTE: Velocity, and therefore linear momentum, is always relative to the frame of reference. For a more complete discussion about velocity, see the related answer, referenced below, entitled 'How to Find Velocity'..Angular momentum is a pseudovector quantity that describes the momentum of an object that is spinning or rotating in place. An object has angular momentum only when it is spinning, or rotating about an axis. When an object is not spinning or rotating, then it does not have angular momentum..It is possible for an object to have only linear momentum, only angular momentum, or both angular and linear momentum. Note that this discussion falls apart in quantum mechanics, so we are only discussing classical physics - that is, every day observable objects, and not light particles (photons), electrons, or other quantum particles..All objects do have inertia, which is a resistance to a change in its momentum.
bohrs momentum value?
Assuming circular orbits, Bohr proposed that the angular momentum L of an electron in its orbit is quantized, that is, it has only specific, discrete values. The value for L is given by the formula L=mevrn=nh2π(n=1,2,3,…)
