Thanks Labappara team for manufacturing outstandnding Lab instruments and supporting me with various product range with best quality and rates of various equipment for my analytical lab (Dr.Arjun singh )Custom design Labappara products in my chemistry lab with students for research purpose give good result as per requirement. The moment of inertia of this can thus be given by, The bob was then moved 5° then released to oscillate to attain stability in motion such that its motion is only in one direction, parallel to the protractor. Simple Pendulum Experiment.
A graph is drawn with l along X axis and TA second’s pendulum is one for which the period of oscillation is 2 seconds. To calculate the acceleration due to gravity at a place; The Theory What is a Simple Pendulum? If we suspend a mass at the end of a piece of string, we have a simple pendulum. The gravitational pull on the mas object was done by manipulation of the length of the bob from the fixed point O and the angular displacement. Registered Data Controller No: Z1821391. Registered office: Venture House, Cross Street, Arnold, Nottingham, Nottinghamshire, NG5 7PJ.
Bring its hands to the zero position.Move bob using the hand at an angle not more than 45The stop watch is started when the pendulum crosses the equilibrium position to any one side.When it passes the equilibrium position in the same direction the next time it has completed one oscillation.Just when the 20th oscillation is complete, count 20 and at once stop the stop watch.Note the total time taken for twenty oscillations from the position of both the hands of the watch.As we need two observations for the same length, repeat steps 12 to 15 one more time.Repeat the experiment for lengths 60cm, 70cm, 80cm, 90 cm, 100cm, 110 cm, 120cm and 130cm.In each case is calculated. They are responsive, flexible and deliver high qualtiy products on time. of the bob, is called the length of the simple pendulum.
The effective pendulum length, was given by the length of the string from the pivot to the top of the bib and the distance from the center of the mass to the top of the bob.
The simple pendulum experiment aim is to investigate how the period of oscillation relates to the displacement angle and to find the gravitational acceleration due to the gravity of a swinging object about a point.
The trend line equation of the experiment shows a general linear equation, interpreted that the time taken to complete one oscillation is directly proportional to the length of the pendulum (Aggarwal, Verma & Arun, 2005). It is represented by the letter T.The time period of a simple pendulum depends on the length of the pendulum (l) and the acceleration due to gravity (g), which is expressed by the relation,If we know the value of l and T, we can calculate the acceleration due to gravity, g at that place.We can plot a graph between l and T2 by taking l along the X axis and T2 along the Y axis.
The uncertainty in the periods for these sets is the one calculated initially. This experiment uses the simple pendulum setup to measure the acceleration due to gravity from Newton’s second law of motion. The time taken for 20 swings was then recorded three times, keeping the same length of the pendulum (1m). It is represented using the aphabet ( l ).Time period is the time taken by the bob of the simple pendulum to make one complete oscillation. Additionally, the experiment also examines how the period of oscillation,

Rstad Side 1 av 4 Simple Pendulum Investigation of gravity and restori ng force Aim To determine acceleration due to gravity by measuring the time period of a simple pendulum. The period for 20 complete oscillations was measured, and record and the procedures repeated to obtain six consistent readings while taking turns between the colleagues to give everybody a chance and avoid errors. Simple pendulum: Objective. The recorded results were analyzed in an excel paper, and the results indicated that as the length of the pendulum l and the angle of displacement
EXPERIMENT 2 Measurement of g: Use of a simple pendulum OBJECTIVE: To measure the acceleration due to gravity using a simple pendulum. This process was tiresome to come up with consistent readings, could be simulated in CAD software like inventor to obtain accurate, consistent results faster (Ganley, 1985).

A simple pendulum is defined to have an object that has a small mass, also known as the pendulum bob, which is suspended from a light wire or string, such as shown in Figure 1.
We set the length of the string to 400mm.
Lesson 7 - The Simple Pendulum, Oscillating Things - Demonstrations in Physics - … The period of oscillation T was calculated together with the uncertainty T from the excel spreadsheet data and results recorded.
