How does a pendulum work? A pendulum works by converting energy back and forth, a bit like a rollercoaster ride. When the bob is highest (furthest from the ground), it has maximum stored energy (potential energy).As it accelerates down toward its lowest point (its midpoint, nearest the ground), this potential energy is converted into kinetic …

Period of motion. In general, the period of the simple pendulum depends on the amplitude of its motion. For small amplitude oscillations, the simple pendulum equation ((10.3)) reduces to the simple harmonic oscillator equation (10.5), and the period becomes independent of amplitude. The general solution of the simple harmonic …

A pendulum in simple harmonic motion is called a simple pendulum. A pendulum has an object with a small mass, also known as the pendulum bob, which hangs from a light wire or string. The equilibrium position for a pendulum is where the angle θ θ is zero (that is, when the pendulum is hanging straight down). It makes sense that without any ...

The Simple Pendulum. A simple pendulum is defined to have a point mass, also known as the pendulum bob, which is suspended from a string of length L with negligible mass (Figure (PageIndex{1})). Here, the only forces acting on the bob are the force of gravity (i.e., the weight of the bob) and tension from the string.

L is the length of the pendulum (of the string from which the mass is suspended); and; g is the acceleration of gravity. On Earth, this value is equal to 9.80665 m/s² — this is the default value in the simple pendulum calculator. You can find the frequency of the pendulum as the reciprocal of the period: f = 1/T = 1/[2π√(g/L)]
