Angular acceleration; (Aa) The increase rate of velocity applied to a mass experiencing angular mometum
Angular Momentum: (Am) a force created by the interruption of a mass in radial motion,usually viewed as decreasing orbital path.
Angular Velocity; (Av) The speed of a mass experiencing a change in trajectory.
Balance: a point of rest for an object that is not moving, a pendulum or wheel is "balanced" when at rest.
Center of Gravity: (COG) A point within a mass that is equal-distance in all directions of its properties, not its physical center.
Centrifugal force: (Cf) The force pulling on the axis of a weight traveling in radial path.
Centripetal force: (Cp) A true physical barrier or containment holding, retaining or changing the radial path of a weight in radial motion.
Driver: A secondary device or weight mass used to actively-move a lever,cross bar, weight etc.
Impetus 1. An impaling force; impulse 2. The force or energy associated with a moving body. 3. Something that incites; stimulus.
Impressed: 1. To affect strongly, often favorably 2. To produce vivid impression of. 3. To mark or stamp with or as if with pressure. 4. To apply with pressure 5. To compel 6. To confiscate (properties)
Load: The negative torque applied to the output of a motor, usually measured in foot pounds or inch pounds,
priori: 1. Preceding in time or order 2, Preceding in importance or value
Prony Brake: a device used to measure output torque of a motor or machine in foot pounds.
