In this interactive activity adapted from the University of Utah's ASPIRE Lab, learn about amplitude. In the case of an object moving back and forth, such as a pendulum, the amplitude of the motion is the distance from equilibrium to maximum displacement. Adjust the amplitude of a swinging pendulum and see how the resulting waveform changes. Next, adjust the volume control to hear sounds of different amplitudes and see the corresponding waveforms.
