What is another word for physical pendulum?
Pronunciation: [fˈɪzɪkə͡l pˈɛndjʊləm] (IPA) 
A physical pendulum is defined as a body suspended from a pivot point, capable of oscillating back and forth under the influence of gravity. Other synonyms for this term include harmonic oscillator, simple pendulum, and torsion pendulum. A harmonic oscillator refers to a system wherein the motion is periodic, following a regular pattern. A simple pendulum is distinguished by a mass attached to a string or wire which oscillates in a single direction. A torsion pendulum, on the other hand, is a pendulum that rotates around an axis, typically due to the force of torsion. Each of these terms is used to describe a physical pendulum in different settings, depending on its motion and properties.
