Law of _______ body in a stat of rest or uniform motion will continue in the same state unless compelled to change by forces applied to itInertia (newton's 1st law)
Law of _______ body’s change in motion is proportional to the motive force appliedAcceleration (newton's 2nd law)
Law of __________ for every action there is an equal and opposite reactionAction and Reaction (newton's 3rd law)
The center of resistance of a tooth is located approximately ____ the length of the embedded root when measured from the alveolar crest1/2
A tooth is restrained by its periodontal attachment, therefore its center of mass does not equate to its ____ ____ _____Center of Resistance (center of rotation)
The tendency of a body (or tooth) to rotate when a force is applied at a distance from the Center of Resistance is called it ______ _____rotational moment
Force * perpendicular distance from COR = _______moment
The moment of a couple is calculated by multiplying the distance between the two forces by the magnitude of ____one (of the forces)
if the moment produced by the couple in the bracket (counter-moment) is equal to the moment produced by the force moving the tooth, the tooth will be _______ translated
If the moment produced by the couple in the bracket is less that the moment produced by the force moving the tooth will be ______tipped
If the moment produced by the couple in the bracket is greater than the moment produced by the force, then _____ movement will be producedroot
