- 1The "resistance to acceleration" and is directly proportional to a body's/object's massInertia
- 2The _______ the mass, the larger the inertiaLarger
- 3The "resistance to angular resistance" and is directly proportional to the massAngular acceleration
- 4The more _____ mass is distributed to the axis of rotation the ______ it is to initiate or stop angular motionClosely
Easier - 5What does swinging a weighted bat do to its inertiaCreates a larger moment of inertia than a regular bat
- 6The formula for momentum isM=mv
- 7The formula or angular momentumH=msqauredxw
H=angular momentum
r or (k)=radius
w= angular velocity - 8Distance from axis of rotation to a point where the body's mas could be concentrated without altering its rotational characteristicsRadius of Gyration
- 9Quantity of angular motion possessed by a body; measured as the product of momentum of inertia and angular velocityAngular Momentum
- 10When gravity is the only acting force, the angular momentum stays the same it isConserved
This does not mean that the components that comprise H cannot change-but the resultant H must stay the same. It may be obvious, but it’s not usually the mass that will change; it is either the radius of gyration or the angular velocity. - 11If angular velocity goes up then radius of gyration goesDown
We spin faster if we tuck vs layout - 12Type of rotation causes rotation about two axes simultaneouslyCat rotation
