define angular bicentum and equation
Answers
Answer:
Linear momentum (p) is defined as the mass (m) of an object multiplied by the velocity (v) of that object: p = m*v. With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.

Answer:
Momentum is the product of mass and the velocity of the object. Any object moving with mass possesses momentum. The only difference in angular momentum is that it deals with rotating or spinning objects.
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 axis. Here the angular momentum is given by:
L⃗ =I×ω⃗
Where,
L⃗ is the angular momentum.
I is the rotational inertia.
ω⃗ is the angular velocity.
Explanation:
Angular momentum is defined as:
The property of any rotating object given by moment of inertia times angular velocity.
