Abduction/Adduction is in what plane of motion?

• Sagittal

• Frontal

• Coronal

• Transverse

Angular inertia is

• Mass and distribution

• Weight and distribution

• Mass and moments

• Weight and torque

More angular inertia requires more torque

• True

• False

Moment of inertia is

• Force*distance

• Mass*radius of gyration

• Mass/radius of gyration

• Weight*radius of gyration

A moment arm is

• Longitudinal distance to axis of rotation

• Opposite distance to axis of rotation

• Perpendicular distance to axis of rotation

• Inferior distance to axis of rotation

Do we need more torque if we have higher moment of inertia

• True

• False

Angular momentum is

• Mass*velocity

• Angular acceleration*moment of inertia

• Moment of inertia*angular velocity

• None of these

Moment of inertia * angular acceleration equals

• Angular momentum

• Torque

• Angular inertia

• Force

Angular impulse is

• Force*time

• Torque*time
