- Place the clamp stand on the table.
- Clamp the split cork firmly to the clamp stand such that the line of separation between the two pieces of the split cork is at right angles to the line OA along which the pendulum oscillates as given in the figure.

## 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 pendulum in physics class 11?

A simple pendulum can be described as a device where its point mass is attached to a light inextensible string and suspended from a fixed support. The vertical line passing through the fixed support is the mean position of a simple pendulum.

## What is the analysis of simple pendulum experiment?

Abstract: A Simple Pendulum is a piece of mass attached to a thread and supported rigidly from one end. Simple pendulum experiment is mainly carried out for calculating the time period of an oscillation, when there is a change in the amplitude.

## What is the conclusion of simple pendulum experiment?

Answer: The surprising conclusion – the pendulum traverses a longer distance in a shorter time, than in a shorter distance, and its period is shorter. … This friction slowed down the pendulum’s faster movements and led to a decrease in the length of the arc through which it passed.

## What is the motion of pendulum?

Oscillatory motion is the type of motion in which an object moves to and fro about a fixed point. The swinging of a pendulum is an example of oscillatory motion.

## What is simple pendulum explain with diagram?

A simple pendulum has a heavy point mass (known as bob) suspended from a rigid support by a massless and inextensible string. When the bob from its mean position is pulled to one side and then released, the pendulum is set to motion and the bob moves alternately on either side of its mean position.

## Which type of motion is simple pendulum?

The simple pendulum is another mechanical system that moves in an oscillatory motion.

## What is called simple pendulum?

Definition of simple pendulum : an ideal pendulum consisting of a point mass suspended by a weightless inextensible perfectly flexible thread and free to vibrate without friction โdistinguished from physical pendulum.

## What is the objective of 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.

## What is the introduction of simple pendulum?

Introduction. A simple pendulum consists of a small bob of mass (m) suspended by a light (assumed to be massless) string of length (L), and the string is firmly attached at its upper end. This pendulum is a mechanical system which we will assume exhibits simple harmonic motion.

## Why do we study simple pendulum?

The pendulum is important to measure the effects of gravity. Galileo observed that the reason a pendulum moves back towards the resting position is due to the gravitational pull of the earth. The spinning of the earth can be demonstrated using a pendulum.

## What is the formula of time period of oscillation?

time is called T, the period of oscillation, so that ฯT = 2ฯ, or T = 2ฯ/ฯ. The reciprocal of the period, or the frequency f, in oscillations per second, is given by f = 1/T = ฯ/2ฯ.

## How do you draw a simple pendulum graph?

## What is effective length of a pendulum?

The effective length of a simple pendulum is the sum of the following three: length of string, radius of bob, and length of hook. In a simple pendulum experiment, the length of the string, as measured by a meter scale, is 92.0cm.

## How do you find the gravity of a pendulum?

Measure the time period T for one oscillation using a stopwatch. Determine the length L of the pendulum. Divide the length L by the square of the time period T . Multiply the value obtained from Step 3 by 4ฯยฒ and you will get the value for acceleration due to gravity, g .

## What are the precautions for simple pendulum?

- The bob of pendulum should be displaced with a small angle.
- The amplitude of the oscillation of a simple pendulum should be small.
- Fans should be switched off to reduce the air resistance.
- The simple pendulum should be oscillate in a vertical plane only.

## What is the conclusion of acceleration due to gravity?

All objects, irrespective of their mass, experience the same acceleration g when falling freely under the influence of gravity at the same point on the Earth. Close to the Earth’s surface, g=9.8 m sโ2.

## Does pendulum period depend on angle?

Finally, the angle that the pendulum swings through (a big swing or a small swing) does not affect the period of the pendulum because pendulums swinging through a larger angle accelerate more than pendulums swinging through a small angle.

## How many types of pendulum are there?

The various kinds of pendulums include the bifilar pendulum, the Foucault pendulum, and the torsion pendulum.

## What affects pendulum period?

The mass and angle are the only factors that affect the period of a pendulum.

## What is the frequency of a simple pendulum?

Frequency f of a simple pendulum depends on its length โ and acceleration g due to gravity according to the following equation f=2ฯ1lg .

## Why pendulum is used in clock?

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 define 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.

## What is the dimension of simple pendulum?

The period of a simple pendulum is given by T=2ฯgl , where l is length of the pendulum and g is acceleration due to gravity. Show that this equation is dimensionally correct.
