write a note about angular momentum......
Answers
Answer:
Angular momentum is a vector, like Force, momentum and velocity. Its direction is determined by the so-called right hand rule. ... Note if w represents an angular velocity of 2pi radians/second, 2pi x r is just the circumference of a circle, so at that rate of rotation the object makes one complete circle in one second.

If you try to get on a bicycle and try to balance without a kickstand you are probably going to fall off. But once you start pedalling, these wheels pick up angular momentum. They are going to resist change, thereby balancing gets easier.
Angular momentum is defined as:
The property of any rotating object given by moment of inertia times angular velocity.
It is the property of a rotating body given by the product of the moment of inertia and the angular velocity of the rotating object. It is a vector quantity, which implies that here along with magnitude, the direction is also considered.
Symbol The angular momentum is a vector quantity, denoted by L⃗
Units It is measured using SI base units: Kg.m2.s-1
Dimensional formula The dimensional formula is: [M][L]2[T]-1

Angular Momentum Formula
Angular momentum can be experienced by an object in two situations. They are:
Point object: The object accelerating around a fixed point. For example, Earth revolving around the sun. Here the angular momentum is given by:
L⃗ =r×p⃗
Where,
L⃗ is the angular velocity
r is the radius (distance between the object and the fixed point about which it revolves)
p⃗ is the linear momentum.
Extended object: The object, which is rotating about a fixed point. For example, Earth rotates about its
