The lengths of the pendulums are set such that in a given time t, the first pendulum completes n oscillations, and each subsequent one completes one more oscillation than the previous. As all pendulums are started together, their relative phases change continuously, but after time t, they come back in sync and the sequence repeats. [1]
A pendulum is a body suspended from a fixed support such that it freely swings back and forth under the influence of gravity. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back towards the equilibrium position.
The equation of the simple harmonic motion with frequency for the displacement () is given by ¨ + =. If the frequency is constant, the solution is simply given by = (+).But if the frequency is allowed to vary slowly with time = (), or precisely, if the characteristic time scale for the frequency variation is much smaller than the time period of oscillation, i.e., | |, then it can be shown ...
The parameter stands for in an ideal pendulum, and in a compound pendulum, where is the length of the pendulum, is the total mass of the system, is the distance from the pivot point (the point the pendulum is suspended from) to the pendulum's centre-of-mass, and is the moment of inertia of the system with respect to an axis that goes through ...
The equation for describing the period: = shows the period of oscillation is independent of the amplitude, though in practice the amplitude should be small. The above equation is also valid in the case when an additional constant force is being applied on the mass, i.e. the additional constant force cannot change the period of oscillation.
"Simple gravity pendulum" model assumes no friction or air resistance. A pendulum is a device made of a weight suspended from a pivot so that it can swing freely. [1] When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position.
The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum, and also to a slight degree on its weight distribution (the moment of inertia about its own center of mass) and the amplitude (width) of the pendulum's swing.
The same point is called the center of oscillation for the object suspended from the pivot as a pendulum, meaning that a simple pendulum with all its mass concentrated at that point will have the same period of oscillation as the compound pendulum.
