Introduction
A pendulum clock is a structured pole like rod clock that uses pendulum and hangs vertically
from the top all the end, it has a weight swing that goes sideways because of the force gravity.
Through the force of gravity it exhibits, the pendulum is able to constantly and precisely swing
sideways or back and forth hence making it to be harmonic oscillator (Agarana & Bishop 2015).
Power mechanism
Power mechanism of the pendulum clock is what helps in keeping the clock working or rather
running. The pendulum clock works through the conversion of energy simultaneously. The
maximum the energy that is stored is at when the nod is at the highest point and this is called the
possible potential energy. When the rod of the clock runs downwards near the ground, the energy
is released and it’s converted to kinetic energy (von der Wense , Seiferle & Thirolf 2018). The
nob goes up again to the conversion to potential energy and the cycle continues back and forth.
Though the cycle is influenced by strength of the gravity as well as the length or the distance to
be covered, it takes the same time to finish the swing as the kinetic and the potential energy
keeps swinging from the one form of energy to the other. An oscillation is anything that moves
in harmonic motion and works in a similar way as pendulum is called harmonic oscillator.

Wheel train

Wheel train of the pendulum clock is also known as gear train and it enhances improvement of
speed on power mechanism to enable the pendulum to use it. The ratios of the gear train in the
wheel train splits the revolution frequency to provide power to the wheels that alternates once
every hour in twelve hours. A Pendulum clocks is usually made up of three wheels, they include:
the center wheel, the third wheel and the escape wheel.
The rotation and cycling of the Centre wheel is once in an hour, third wheel once in one minute
while the escape wheel ensures that the mainspring unwinds speed is acknowledged and then
regulated. (Huygens, 2015)
Escapement wheel
Escapement wheel-An escapement is an automated connection line in clocks or watches that
helps in ensuring the release and discharges of impulses of the timekeeping elements on the
clock.
Oscillators
One of the most commonly used oscillators is the pendulum of a clock. If you push on a
pendulum to start it swinging, it will oscillate at some frequency -- it will swing back and forth a
certain number of times per second (Whitestone 2012). The length of the pendulum is the main
thing that controls the frequency.
Pendulum clock is widely used by the past and the present generation globally as it is eases the
tracks keep of time through observing the swing rod completion.
