## What is simple pendulum explain its working?

A simple pendulum consists of a metal bob hung by a string connected to a pivot point.

The bob oscillates in to and fro motion because of its mass and momentum.

…

The number of oscillation the pendulum completed in one second is its frequency and the time required for one complete oscillation is called the time period..

## What is a simple pendulum used for?

Pendulums are in common usage. Some have crucial uses, such as in clocks; some are for fun, such as a child’s swing; and some are just there, such as the sinker on a fishing line. For small displacements, a pendulum is a simple harmonic oscillator.

## Why do we use small angle in simple pendulum?

In the case of a pendulum, if the amplitude of these cycles are small (q less than 15 degrees) then we can use the Small Angle Approximation for the pendulum and the motion is nearly SHM. … The reason this approximation works is because for small angles, SIN θ ≈ θ.

## How do you calculate pendulum?

How to analyze a pendulum in swingDetermine the length of the pendulum. … Decide a value for the acceleration of gravity. … Calculate the period of oscillations according to the formula above: T = 2π√(L/g) = 2π * √(2/9.80665) = 2.837 s .Find the frequency as the reciprocal of the period: f = 1/T = 0.352 Hz .More items…

## What is the pendulum problem?

a Piagetian task used to assess cognitive development. The participant is asked to work out what governs the speed of an object swinging on a piece of string.

## What is the relationship between mass and period of a pendulum?

The period of a pendulum does not depend on the mass of the ball, but only on the length of the string. Two pendula with different masses but the same length will have the same period. Two pendula with different lengths will different periods; the pendulum with the longer string will have the longer period.

## What is period of oscillation?

The time to complete one oscillation remains constant and is called the period T. Its units are usually seconds, but may be any convenient unit of time.
