# What is a simple pendulum class 11 physics?

Imagine a pendulum. The higher you lift it in one direction, the more power to swing up on the other side will you give it. You will perhaps notice the power in it’s weight and resistance, more when you let it go. It is with feelings as with the pendulum – they swing!

## What is simple pendulum in physics definition?

pendulum, body suspended from a fixed point so that it can swing back and forth under the influence of gravity. Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant.

## What is a simple pendulum example?

The forces acting on the bob of a pendulum are its weight and the tension of the string. It is useful to analyze the pendulum in the radial/tangential coordinate system. The tension lies completely in the radial direction and the weight must be broken into components.

## What is simple pendulum and how it works explain with diagram?

Imagine a pendulum. The higher you lift it in one direction, the more power to swing up on the other side will you give it. You will perhaps notice the power in it’s weight and resistance, more when you let it go. It is with feelings as with the pendulum – they swing!

## Why is it called a simple pendulum?

The simple pendulum (see wikipedia or hyperphysics) leads to a simple differential equation by using Newton’s second law: ¨θ+glsin(θ)=0. This pendulum gives the easiest way te look at harmonic motion. The above case is what they call the simple pendulum.

## What is the law of simple pendulum?

According to the laws of simple pendulum. A simple pendulum’s period is directly proportional to the square root of its length. A simple pendulum’s period is inversely related to the square root of gravity’s acceleration. A simple pendulum’s period is independent of its mass.

## What is a simple pendulum and its time period?

The time taken by a freely oscillating pendulum to complete one. oscillation is called Time period Its SI unit is second (s) It is numerically. the reciprocal of frequency of oscillations.

## How do you do simple pendulum experiments Class 11?

Mark a point A on the table (use a chalk) just below the position of bob at rest and draw a straight line BC of 10 cm having a point A at its centre. Over this line bob will oscillate. Find the least count and the zero error of the stop clock/watch. Bring its hands at zero position.

## What is simple harmonic motion class 11?

Simple Harmonic Motion (SHM) is a periodic rotation about the mean position of the body that shifts to and fro. On the oscillating body, the restoring force is directly proportional to its displacement and is therefore oriented towards its mean direction.

## What is the conclusion of simple pendulum experiment?

The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. There are a number of reasons why Galileo thought that the period remains constant. One factor which Galileo failed to consider is friction.

## What is the motion of a pendulum?

Imagine a pendulum. The higher you lift it in one direction, the more power to swing up on the other side will you give it. You will perhaps notice the power in it’s weight and resistance, more when you let it go. It is with feelings as with the pendulum – they swing!

## What kind of motion does a simple pendulum execute?

The forces acting on the bob of a pendulum are its weight and the tension of the string. It is useful to analyze the pendulum in the radial/tangential coordinate system. The tension lies completely in the radial direction and the weight must be broken into components.

## What is the frequency of a simple pendulum?

Frequency f of a simple pendulum depends on its length ℓ and acceleration g due to gravity according to the following equation f=2π1lg .

## How many forces are acting on a simple pendulum?

There are two dominant forces acting upon a pendulum bob at all times during the course of its motion. There is the force of gravity that acts downward upon the bob. It results from the Earth’s mass attracting the mass of the bob. And there is a tension force acting upward and towards the pivot point of the pendulum.

## What are the parts of a simple pendulum?

A simple pendulum consists of mainly three parts. A bob, which is having a small mass, a string which suspends the bob and a fixed support to which the string containing the bob is tied firmly.

## Why does a pendulum swing?

This is because the swinging motion of a pendulum is due to the force of gravity generated by the earth’s size. Other factors, including a pendulum’s length, can also affect its motion. A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity.

## Who invented simple pendulum?

Being bedridden is never much fun, but sometimes it can lead to scientific insight. Such was the case with 17th century Dutch astronomer Christiaan Huygens.

## What are the four laws of simple pendulum?

• 1st law or the law of isochronism: The time period of the simple pendulum is independent of the amplitude, provided the amplitude is sufficiently small.
• 2nd law or the law of length:
• 3rd law or the law of acceleration:
• 4th law or the law of mass:

## Which law does the swinging pendulum follow?

This principle is called the law of conservation of energy. We can use a simple pendulum to observe the conservation of energy in action. A pendulum has two types of energy: potential energy, which is stored energy; and kinetic energy, the energy of motion.

## Who gave the law of oscillation of pendulum?

Galileo Galilei The Law of the Pendulum Italian mathematician, astronomer, physicist and inventor Galileo Galilei lived from 1564 to 1642. Galileo discovered the “isochronism of the pendulum” aka the “law of the pendulum”.

## Why time period of simple pendulum is constant?

Time period of a given pendulum is always constant because it depends on the length of the pendulum.

## How do you find time in a simple pendulum?

1. Determine the length L of the pendulum.
2. Divide L by the acceleration due to gravity, i.e., g = 9.8 m/s² .
3. Take the square root of the value from Step 2 and multiply it by 2π .
4. Congratulations! You have calculated the time period of a simple pendulum.

## What is the definition of time period?

Noun. time period (plural time periods) The length of time during which an activity occurs or a condition remains. It may be measured either in seconds or in millions of years, depending upon the nature of the activity of condition being considered.

## What is the objective of the simple pendulum experiment?

The goal of this experiment was to determine the effect of mass and length on the period of oscillation of a simple pendulum. Using a photogate to measure the period, we varied the pendulum mass for a fixed length, and varied the pendulum length for a fixed mass.
