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

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.
Best on the results findings, it showed that the Rafin Tambari has the highest value of acceleration due to gravity which is User Settings.
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. We transcribed the measurements from the cell-phone into a Jupyter Notebook.
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.

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. Torque and angular acceleration of a fly wheel Torsional oscillations in different liquids Moment of Inertia of Flywheel Newton's Second Law of Motion Ballistic Pendulum Collision balls Projectile Motion Elastic and Inelastic Collision Electric Circuits Virtual Lab Pilot An electric circuit is composed of individual electrical components such as resistors, inductors, capacitors etc to trace the current that flows through it.

Another limitation was friction which cannot be obviously ignored. Finally, it was possible to demonstrate a self-consistency between the experimental and numerical results of the system studied in this work. After the we determined the mass of pendulum and also form these values of k we mesured the moment of inertia. The various results that I have found, reveals that the average value of acceleration due to gravity for Azare area of Katagum Local Government is 9. Mensuration From Everand. From the center of gravity, there are nine holes on each side left and right. Arrange the clamp stand to hold metal rod. Journal of Endocrinology and Metabolism Research. Introduction: A rigid body with distributed mass able to freely pivot about a horizontal axis which does not coincide with the centre of gravity is called a compound pendulum [1]. Experiment number: 08 Experiment name: Determination of the value of g acceleration due to gravity by means of compound pendulum. Second, the approach of the analytical model to compare with the experimental results. Did you find this document useful? Uploaded by Numan

Use a precision stopwatch and note the time accurately as far as possible. A measurement of g with a ring pendulum. Ensure that the pendulum oscillates in a vertical plane and that there is no rotational motion of the pendulum. The results showed that the value of acceleration due to gravity "g" is not constant; it varies from place to place. The students found a didactic and different way of studying the physical pendulum. Catharina Faber. Presented by Presented by. Academic Documents. Arrange the clamp stand to hold metal rod. Journal of European Integration Partners at Paris? Displace the bar pendulum setup slightly approx. Phy 11 Phy This work is primarily one utility of a theory for conversion of mechanical energy into electrical energy.
