Angular momentum/inertia concepts

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.

Front

What is the formula for Angular Momentum?

Back

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

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.

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.

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.

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.

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.

Front

What is the effect of speed on stability while riding a bicycle?

Back

At higher speeds, the angular momentum of the wheels increases, providing greater stability to the bicycle.

Front

What is the difference between linear speed and angular speed?

Back

Linear speed refers to how fast an object moves along a path, while angular speed refers to how fast an object rotates around an axis.

Front

How does the distribution of mass affect Rotational Inertia?

Back

The further the mass is distributed from the axis of rotation, the greater the rotational inertia.
