Question

What is one oscillation of a pendulum?

Answer 1

Hint:A pendulum is a weight that is suspended from a pivot and may freely swing. When a pendulum is pushed sideways from its resting, equilibrium position, gravity acts as a restorative force, accelerating the pendulum back to its equilibrium position. The restoring force acting on the mass of the pendulum causes it to oscillate about the equilibrium position, swinging back and forth, when it is released. The time for one complete cycle, a left swing and a right swing, is termed the period. The period is determined by the length of the pendulum and, to a lesser extent, by the amplitude, or swing breadth.

Complete answer:
Oscillation is the periodic fluctuation of a measure around a central value (often a point of equilibrium) or between two or more states, usually in time. Mechanical oscillation is exactly described by the term vibration. A swinging pendulum and alternating current are both instances of oscillation.

A pendulum completes one oscillation when it begins at one extreme position A, travels to the opposite extreme point B, and then returns to A. The time period is the amount of time it takes to complete one oscillation. The oscillation's time period remains constant.

Oscillations can be found in virtually every field of science, including the beating of the human heart (for circulation), business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, string vibrations in guitars and other string instruments, periodic firing of nerve cells in the brain, and the periodic firing of nerve cells in the brain.

Note:A 1st-century seismometer devised by Han Dynasty Chinese scholar Zhang Heng is one of the oldest documented applications of a pendulum. Its job was to sway and trigger one of a series of levers after being jolted awake by a distant earthquake. A tiny ball would fall out of the urn-shaped device into one of eight metal toad's mouths below, at the eight points of the compass, indicating the direction the earthquake was situated, after being released by a lever.
