The attribute of any rotating object determined by the product of the moment of inertia and the angular velocity is known as angular momentum.
<h3>What is Angular Momentum?</h3>
- Without a kickstand, attempting to balance while getting on a bicycle will definitely result in you falling off. However, these wheels gain angular momentum once you begin pedaling. They're going to be resistant to change, which will make balance simpler.
- The definition of angular momentum is: any rotating object's characteristic determined by moment of inertia times angular velocity.
- It is a characteristic of rotating bodies determined by the sum of their moment of inertia and angular velocity. Since it is a vector quantity, the direction must also be taken into account in addition to the magnitude.
- Angular Momentum Examples : We encounter this property frequently, whether knowingly or unknowingly.
- The following provides some examples : Ice-skater
- In order to begin a spin, an ice skater starts with her hands and legs spread widely from the center of her body. She moves her hands and leg closer to her body when she needs to spin with more angular velocity, though.
- As a result, she conserves angular momentum and spins faster.

Answer:
A- Martin brings his friends home to meet grandpa.
Explanation:
took the test.
The train’s average speed is 80km/h
To develop this problem it is necessary to apply the concepts related to Gravitational Potential Energy.
Gravitational potential energy can be defined as
As M=m, then
Where,
m = Mass
G =Gravitational Universal Constant
R = Distance /Radius
PART A) As half its initial value is u'=2u, then
Therefore replacing we have that,
Re-arrange to find v,
Therefore the velocity when the separation has decreased to one-half its initial value is 816m/s
PART B) With a final separation distance of 2r, we have that
Therefore
Therefore the velocity when they are about to collide is 
No, because the energy is the capacity for performing work. Gravity is the force that draws everything to the earth's center.
