The motion of a pendulum in water will be similar to what it is in air, except it will move more slowly and loose energy much more rapidly (unless something with some "power" is keeping it going). The speed of the pendulum should graph like a sine wave with the peaks and troughs denoting the endpoints of the travel of the pendulum in its arc. The slope of the curve at any point will represent the instantaneous acceleration. If the pendulum is released and no energy is put in from outside, the graph of the speed will diminish very quickly and dramatically.
A simple pendulum exhibits simple harmonic motion
A simple pendulum undergoes simple harmonic motion only for small amplitudes because for small amplitudes the motion almost reduces to a straight line motion. Simple harmonic motion means motion on a straight not on curves
A pendulum moves in simple harmonic motion. If a graph of the pendulum's motion is drawn with respect with respect to time, the graph will be a sine wave. Pure tones are experienced when the eardrum moves in simple harmonic motion. In these cases "wave" refers not to the thing moving, but to the graph representing the movement.
1). Air resistance 2). Friction in the pivot. These two effects rob energy from the pendulum. Without air resistance or friction in the pivot, a pendulum, once set in motion, would not stop.
motion of a simple pendulum
transverse wave is an example of pendulum motion.
The motion of the simple pendulum will be in simple harmonic if it is in oscillation.
In actual conditions, a pendulum's motion can be seen as periodic, but decaying.
