Vibration Any motion that repeats itself after an interval of time is called vibration or oscillation.

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.

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.

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. In this experiment the value of g, acceleration due gravity by means of compound pendulum is obtained and it is Which is a negotiable amount of error but it needs to be justified properly.

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. Also, during the discussion of the practical, the students were taught how to derive the complex Time period T to gravitational acceleration g relationship for a compound pendulum which has been stated below. The mass of simple pendulum is concentrated in its bob while the mass of a compound pendulum is distributed evenly over its entire body.

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.
