A swinging pendulum encounters "friction" called drag in air. It will do so in water, too. It's just that the viscosity of the air is so much less than that of water, so the pendulum moves with a ton more drag in water. It will move much more slowly in water, and will come to a stop dramatically sooner than an identical pendulum swung in air.
time taken for this pendulum to come to a complete stop in water will be shorter than swingging in air because water bouyant force and water resistance are greater than air friction.
the period
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
Using a pendulum as an example: a pendulum swings from left to right (first swing) and then swings back again right to left (second swing). A complete oscillation is composed of both swings.
The frequency of a pendulum is 1 divided by (the number of seconds to make one complete swing)
The pendulum acts as an escape(Anchor) mechanism faciltating the movements of the clock - face e.g. the hour and minute hands . "An escapement is the mechanism in a mechanical clock that maintains the swing of the pendulum and advances the clock's wheels at each swing. " Excerpt from Wikipedia . See links .
The pendulum will take more time in air to stop completely in comparision with water
All pendulums swing. They wouldn't be pendulums if they didn't.
it all has to do with a pendulum when you swing back and forth you are using potenial and kinetic enery

At the low point of a swinging pendulum, the type of energy being demonstrated is maximum kinetic energy. It has zero potential energy at this point of the swing.

As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.
