Increased Angular velocity, increased rotational inertia
Increased Angular velocity, decreased rotational inertia
What happens to her moment of inertia when a figure skater brings in her arms? (angular momentum= moment of inertia X angular velocity)
Increase her moment of inertia
Decrease her moment of inertia
has no effect
What happens to her angular velocity when a figure skater brings in her arms? (angular momentum= moment of inertia X angular velocity)
Increases her angular velocity
Decreases her angular velocity
Has no effect
