Rigid body dynamics r and velocities v. Select a reference point R and compute the relative position and velocity vectors, The total linear and angular momentum vectors relative to the reference point R are and If R is chosen as the center of mass these equations simplify to To specialize these formulas to a rigid body, assume the particles are rigidly connected to each other so P, i=1...,n are located by the coordinates r and velocities v. Select a reference point R and compute the relative position and velocity vectors, where ω is the angular velocity of the system. The linear momentum and
Constant linear velocity of CLV that is used on the Laserdisc format. The initial specification of CLV (as it applies to laserdisc) results in several playback artifacts to be present in the audio/video portion as well as compatibility problems with Laserdisc players as produced by different manufacturers. In the mid 1980s, Pioneer Electronics introduced the CAA scheme where the speed in rotation of the Laserdisc was lowered in steps and eliminated most playback artifacts and compatibility problems. Since its introduction, most manufacturers of Laserdiscs adopted the CAA format but still referred to their CAA-encoded product as CLV. Constant linear velocity In optical storage,
