FLASHCARD QUESTION

Front

What is Angular Momentum?

Back

Angular momentum is the quantity of rotation of an object and is calculated as the product of its rotational inertia and angular velocity.

2.

FLASHCARD QUESTION

Front

What is the formula for Angular Momentum?

Back

Angular Momentum (L) = Rotational Inertia (I) × Angular Velocity (ω)

3.

FLASHCARD QUESTION

Front

What is Rotational Inertia?

Back

Rotational inertia, also known as moment of inertia, is a measure of an object's resistance to changes in its rotation.

4.

FLASHCARD QUESTION

Front

How does mass affect Angular Momentum?

Back

An increase in mass increases the rotational inertia, which in turn increases the angular momentum if angular velocity remains constant.

5.

FLASHCARD QUESTION

Front

What is the relationship between linear velocity and angular velocity?

Back

Linear velocity (v) is related to angular velocity (ω) by the equation v = r × ω, where r is the radius.

6.

FLASHCARD QUESTION

Front

Why does a kid on the outside of a merry-go-round have greater linear velocity?

Back

The kid on the outside has a larger radius from the center, resulting in a greater linear velocity due to the relationship v = r × ω.

FLASHCARD QUESTION

Front

What happens to Angular Momentum when no external torque is applied?

Back

Angular momentum is conserved; it remains constant if no external torque acts on the system.
