biomechanics

Moment of Inertia is:

• How much angular momentum an object has

• How much angular velocity an object has

• The resistance of a rotating object to change its state of motion

• mass of the object multiplied by the radius of rotation

• C and D

The radius of rotation refers to how the object's _____________ is _____________________ about the _______________________ .

By moving the object's mass ________________ from the axis of rotation, you are ____________________ its radius of rotation and therefore ____________________ its moment of inertia, making the object harder to _________________ .

Angular momentum is the quantity of ___________________ motion possessed by a ______________ body and can be expressed by the formula ________________ velocity x __________________ .

conservation of angular momentum indicates that a rotating body will _______________ to rotate _______________ unless an _______________ acts on it

When a diver leaves the board to when they enter the water, their angular momentum will be

• increased as they are increasing their moment of inertia

• will be conserved as no external forces are acting on them

• will be decreased due to air resistance

• will be increased due to decreasing their moment of inertia and increasing their angular velocity
