PHYSICS 135 Chapter Notes - Chapter 13: Xnet, Tuning Fork, Moving Block
Document Summary
A= and returns. (factor of 2 larger) f. 2 (440 hz) 2760 rad/s (smaller by a factor of 2) A = so the period is 1. 60 s. Identify and set up: the target variables are the period t and angular frequency f, so we can find these using eqs. (13. 1) and (13. 2) Evaluate: the angular frequency is directly proportional to the frequency and the period is inversely proportional to the frequency. Identify and set up: the amplitude is the maximum displacement from equilibrium. In one period the object goes from x. Evaluate: whenever the object is released from rest, its initial displacement equals the amplitude of its shm. Identify: the period is the time for one vibration and. Set up: the units of angular frequency are rad/s. Evaluate: there are 880 vibrations in 1. 0 s, so. Identify: the period is the time for one cycle and the amplitude is the maximum displacement from equilibrium.
