. PERIODIC MOTIONS. 87 116. Trigonometrical Expression for the Amplitude. consider more closely the circular motionof which a simple harmonic motion ofamplitude r and period T may be imaginedto be the projection. On the path AAof the simple harmonic motion as diameterdescribe the circle. Let P be… … While we have deduced this expression from the related circularmotion, it must now be regarded as simply an expression for thesimple harmonic motion of amplitude r and period T.\^{2TT/T)t -\- e\ is called the phase of the simple harmonic motionat time t and e is called the epoch of the simple…
