The y axis shows the sound pressure p (sound pressure amplitude). The reduction of the amplitude is a consequence of the energy loss from the system in overcoming external forces like friction or air resistance and other resistive forces. In damped oscillation, the amplitude of the oscillation reduces with time. The term sinusoidal is used to describe a curve, referred to as a sine wave or a sinusoid, that exhibits smooth, periodic oscillation. Note that the path of the pendulum sweeps out an arc of a circle. The analysis uses all our techniques so far – dimensions (Chapter 1), ... the oscillation period for the pendulum, in the θ→0limit, is ... ‘Is each portion of the formula reasonable, or does it come out of left eld.’ [For non-American readers, left eld is one of the distant reaches of a baseball eld. amplitude between the maximum positive and maximum negative peaks in the signal. The free oscillation possesses constant amplitude and period without any external force to set the oscillation. However, the entire If the graph shows at the x axis the time t, we see the period T = 1 / f. If the graph shows at the x axis the distance d, we see the wavelength λ.
