One thing to keep in mind is that pendulums will not swing forever. It typically hangs vertically in its equilibrium position. As we stated on the previous page, the only thing affecting the period of a pendulum is the length of that pendulum. In advancing forward and running into the stop, the gear will make a sound Here we will be interested in the question What variables affect the period of a pendulum.
The diagram below shows the results of the force analysis for several other positions. For that, it can be demonstrated, by composing the infinitesimal rotations, that the precession rate is proportional to the projection of the angular velocity of Earth onto the normal direction to Earth, which implies that the trace of the plane of oscillation will undergo parallel transport.
The pendulum always has a means of adjusting the period, usually by an adjustment nut c under the bob which moves it up or down on the rod. In all the vibrating systems just mentioned, damping is clearly evident. The simplest way is to imagine tree roots growing down from the soles of each foot rooting you firmly into the Earth.
The extent of its displacement from the equilibrium position becomes less and less over time. The mechanical energy of the bobbing head is lost to other objects. Elastic potential energy is only present when a spring or other elastic medium is compressed or stretched. Its steep northern and southern slopes would allow the experiment to be sited close to its centre of massmaximising the deflection effect.
Vibrational motion is often contrasted with translational motion. Yet, as illustrated by the TME bar, the total amount of mechanical energy is conserved. Energy Analysis In a previous chapter of The Physics Classroom Tutorial, the energy possessed by a pendulum bob was discussed.
But one question that has not yet been answered is the question pertaining to quantities that can be measured.
Christiaan Huygens proved in that the pivot point and the center of oscillation are interchangeable. The velocity is greatest when the displacement is least.
A pendulum is a classic example of an object that is considered to vibrate. An analysis of the plots shows that the velocity is least when the displacement is greatest.
Huygens had discovered in that a pendulum has the same period when hung from its center of oscillation as when hung from its pivot,  and the distance between the two points was equal to the length of a simple gravity pendulum of the same period.
When you inspect the bar charts, it is evident that as the bob moves from A to D, the kinetic energy is increasing and the potential energy is decreasing. The initial force that is imparted to the object displaces it from its resting position and sets it into motion.
The Restoring Force. A vibrating bobblehead often does the back and forth a number of times. The vibrations repeat themselves over and over. As such, the bobblehead will move back to (and past) the equilibrium position every time it returns from its maximum.

Description: The pendulum experiment demonstrates how Eddy currents in a conductor, created by the relative motion between a magnet and the conductor (see Faraday's Law of Induction and Lenz's Law), will resist the motion of the pendulum.I wanted to see how well this works with different types of material and different thickness of the same material.Pendulum experiment
