1
Q
Define moment of inertia
A
The spread of mass from the axis of rotation
2
Q

A
Speed of rotation
3
Q
If a performer increase moment of inertia, what happens to angular velocity?
A
Decreases
4
Q
How can an increase in moment of inertia be achieved?
A
Spreading limbs away from the body
5
Q
If a performer decreases moment of inertia, what happens to angular velocity?
A
Increases
6
Q
How can a decrease in moment of inertia be achieved?
A
Bringing limbs towards the body
7
Q
How can angular momentum be calculated?
A
Moment of inertia x Angular velocity
