Compound pendulum experiment lab report

Vibration Any motion that repeats itself after an interval of time is called vibration or oscillation. Compound pendulum experiment lab report swinging of a pendulum and the motion of a plucked string are typical examples of vibration. The mass of string is negligible in comparison to the bob.

There are many way of measuring this gravity acceleration, but the experiment of compound pendulum is the easiest and effective among them. In the experiment the acceleration due to gravity was measured using the rigid pendulum method.

Then we suspended the pendulum on a support. After this we slightly displaced the pendulum from its mean position through a small angle and released it so that it could vibrate. We measured the time of 10 vibrations and distance from center of gravity to the hole i-e the axis about which the pendulum vibrated. After this we shifted to second hole and repeated the same procedure. Then we calculated the time period T for each hole. Then we plotted a graph between T and G taking T on y axis and L on x axis. From this we calculated the value of g using the formula. Where T represents the time period. After the we determined the mass of pendulum and also form these values of k we mesured the moment of inertia. Length of pendulum was calculated by this formula:. Draw a vertical line with a chalk along the holes of the pendulum or paste a thin white strip of paper but not covering its holes. Focus the eye-piece of the telescope till the cross-wires are'distinctly visible. Now focus the telescope on the.

Enter the email address you signed up with and we'll email you a reset link. The point S is called the centre of oscillation. Conclusion: Gravity acceleration is caused because of the massive body and mass of earth which can be used in many purposes, compound pendulum experiment lab report, because acceleration is one of the major fact and element of force.

A pendulum exhibits simple harmonic motion SHM , which allowed us to measure the gravitational constant by measuring the period of the pendulum. We plan to measure the period of one oscillation by measuring the time to it takes the pendulum to go through 20 oscillations and dividing that by We constructed the pendulum by attaching a inextensible string to a stand on one end and to a mass on the other end. The mass, string and stand were attached together with knots. The uncertainty is given by half of the smallest division of the ruler that we used. We repeated this measurement five times.

By taking values of time period T for one oscillation, we had to plot a distance D to time period T graph. Taking values from the graphs and known formulas, we were able to find the value of gravitational acceleration g and the error in our value. We were also able to calculate the theoretical radius of gyration k and moment of inertia I using the stated derivation of this report. We made sure to take multiple reading whereby we were able to obtain an average reading for all desired values. Now students were to acquaint themselves with the theory of compound pendulum. The practical was aimed at finding the experimental value of gravitational acceleration g and then finding error in our obtained value. It was also aimed at finding the mean radius of gyration k and mean moment of inertia I of the given pendulum. The practical was aimed at giving the students a proper understanding of what gyration is, what the theory behind inertia.

It seems a mysterious and even a magical force. Magnetism's ability to serve mankind especially lies in its relationship to electricity. That means, magnetism and electricity are so closely related to each other. The concept of this can be applied in many technologies for an effective productivity. The study of this lab revolves around the generation, propagation and reception of mechanical waves and vibrations. These concepts embody the study of tiny subatomic particles or lightening fast speeds. They find applications in technologies such as atomic energy or semiconductors. It explains the study of optical properties for different material by adopting laser devices and handling basic aspects of interferometry. It also gives the dynamics of special type of non-linear systems.

Simple Pendulum Simple Pendulum. Also the whole apparatus was also unstable. Theory A pendulum exhibits simple harmonic motion SHM , which allowed us to measure the gravitational constant by measuring the period of the pendulum. Best on the results findings, it showed that the Rafin Tambari has the highest value of acceleration due to gravity which is Theory: Compound pendulum is a rigid body of any shape free to turn about a horizontal axis. Divide the value by the number of vibrations to determine the time period T.

Suriya Suriya. Finally, the theoretical, experimental results and the respective errors obtained by the experiment are shown. Skip carousel. Saarinen Chairs Saarinen Chairs. Third, the development of a dynamic simulator according to the predictions of the theoretical model. The rate of change of velocity per unit of time is called acceleration. Amplitude of vibration should be kept small. Search site Search Search. Phy 11 Phy The acceleration caused by the gravitational attraction of massive bodies, is called acceleration due to gravity [2].
