Figure 5.1: Simple harmonic motion. Shown are the amplitudeA, periodT, and phase constantı. The
horizontal linex.t/D 0 is the equilibrium position.
Figure 5.2: Four common special special cases of simple harmonic motion phase constant. These are physi-
cally identical, and differ only by where the oscillator is in its motion attD 0. (a)Acos.!t/; (b)Acos.!t/;
(c)Asin.!t/; (d)Asin.!t/. In Eq. (5.2), these correspond to: (a)ıD 0 , (b)ıD, (c)ıD=2, (d)
ıD=2.
