Angular Momentum Flashcards

1
Q

How do you calculate angular momentum?

A

Angular momentum possessed by a body is equal to the product of its moment of inertia and its angular velocity.

H = Iω

Q

TRUE or FALSE: Each segment of the body has its own momentum?

A

Q

How can an individual change angular velocity, despite not being able to change angular momentum?

A

An individual can influence moment of inertia which will change angular velocity.
If moment of inertia increases, angular velocity MUST decrease.

Q

What is the relationship between angular acceleration, net moment, and moment of inertia?

A

Angular acceleration is directly proportional to net moment and inversely proportional to moment of inertia.

Q

TRUE of FALSE: if a one body in a closed system looses angular momentum, another must gain angular momentum.

A
