Document Summary

Angular velocity and acceleration linear velocity to angular velocity linear (radial) acceleration constant angular acceleration. A = w ^2r q = q o + w t + a t^2. = w o + a t w ^2 = w o^2a. Displacement, velocity, acceleration are all sinusoidal functions in. Shm: (const)sin(2p t/t + phase, (const)sin(w t + phase) General wave celocity equation w q w w q.
