HOW TO FIND IT:
Torque = Lever Arm x Force applied to the object= r F sin theta --or if you
understand cross products of vectors then Torque = radius x force. |
|
TERMS THAT YOU MUST UNDERSTAND:
Line of Force-- a line drawn that sits on top of the force vector.
Pivot--The point that indicates the axis of rotation or the line the object
rotates about.
Lever Arm-- the perpendicular distance from the pivot to the line of force.
Angular displacement----------------The amount of turning done by an object.
Unit is radians, revolutions, degrees
Angular velocity--omega----------------- The change in angular displacement
divided by the change in time.
Angular acceleration-- (alpha) --------------- The change in angular velocity
divided by the change in time.
Moment of Inertia or Rotational Inertia-- The product of some constant, the
mass of the rotating object & the square of the radius of rotation.
Cross Product-- APC students --see the Vector Page for review!
