Pendulum investigation essay - pendulum investigation introduction in this investigation, i will try to attempt an experiment that will measure the time taken for a pendulum to oscillate for one complete swing i will also explore and investigate the numerous variables that might effect the time taken to oscillate. It was galileo who first observed that the time a pendulum takes to swing back and forth through small distances depends only on the length of the pendulum the time of this to and fro motion, called the period, does not depend on the mass of the pendulum or on the size of the arc through which it swings. Using force= -kx from a simple pendulum, this becomes force=- torsional constant x angular displacement therefore this can definitely be compared to a=-ω 2 x and becomes however therefore i then found out the exact expression which allowed me to directly work out i and k. Research and equations: as we are working in circular motion, rather than linear motion, the equations that will help me investigate the torsional pendulum will have to be derived.
Torsional pendulum essay sample changes to be made to final experiment and reasons to improve reliability of my results i will perform 3 runs for each measurement rather than 1, this will allow me to average the 3 results for each measurement which will improve reliability of results, and if there is one of the 3 that does not fit it can be excluded and average the other 2. To improve reliability of my results i will perform 3 runs for each measurement rather than 1, this will allow me to average the 3 results for each measurement which will improve reliability of results, and if there is one of the 3 that does not fit it can be excluded and average the other 2.
This is a full lab report for the final experiment that was conducted in chem 111 lab, a required and vigorous course for my dietetics major hands-on labs, inc www each of the 7 experiments should be submitted separately one week. Lab report #8 - the simple pendulum - my fit read more about pendulum, experimental, theoretical, errors, determine and length phy 2091-06 experiment performed: oct 4, 2006 report submitted: oct 11, 2006. It is shown in the first part that when a 30 degrees laminar beam of 15 w red laser light passes between a freely moving mass on a torsion pendulum and a fixed mass, there is an increase of the. Oscillation of torsional pendulum essay sample in the final part of the experiment, the oil bath was raised to be in contact with the pendulum disc, and it is. Transient dynamics of centrifugal pendulum vibration absorbers, which are used for reducing torsional vibrations in rotating machines, are investigated using analysis and simulations of a dynamical model.
The aim of this experiment is to measure the acceleration due to gravity using a ticker the remainder of the report is organized as follows physics 215 september 13, 2011 experiment number 3 acceleration due to gravity introduction the purpose of this experiment is to measure. First of all, an experiment essay is performed with a modified bifilar pendulum to study your dynamics, in order to avoid systematics errors in the experimental procedures finally, we perform an. Finally, after establishing these applications, we can examine the similarity between simple harmonic motion and uniform circular motion the torsional oscillator consider a circular disk suspended from a wire fixed to a ceiling.
Pendulum physics to analyze the physics of a pendulum, consider the figure below which shows an arbitrary rigid body swinging back and forth in a plane, about a pivot p this swinging is due to the force of gravity. Torsion pendulum is independent of the amplitude of the motion pendulums (or pendula if we are being exact) of the lab, you should begin by documenting your work into a lab report. Experimental physics modern methods pdf designed for physics students treating the underlying basis for modern techniques and the devices used, this timely survey describes current experimentalexperimental physics: modern methods hardcover october 27, 1988.
This paper looks at the physics behind oscillatory motion and how this can be applied to many different scenarios including using different types of pendulums to explain the phenomena of shm and dhm (simple and damped harmonic motion respectively. The simple pendulum lab report the final project for this course is a formal lab report about one of your labs 53 the modelling of the periodic time decrease as the experiment progressed. Essay writing guide torsional pendulum final experiment investigate the effect of changing the length of wire on the time period for a torsional pendulum.
The pendulum experiment is an experiment about gravity a compound pendulum is a rigid body swinging in a vertical plane about any horizontal axis the purpose of the torsion pendulum experiment is to determine the torsion constant for a given wire. Simple pendulum lab length of a simple pendulum and (5) to determine the acceleration due to gravity using the theory, results, and analysis of this experiment a more accurate timing in this lab, we were able to estimate the value of the acceleration due to. The main objective of the experiment is to study how a hollow shaft would behave compared with the solid shaft, in terms of strength and rigidity under torsion sample calculations table 2: strength and stiffness of hollow and solid shafts having the same outer diameter volume of 12mm diameter solid. Pendulum experiment setup as the pendulum swings back and forth, there is a constant exchange between one example of this motion is the simple pendulum a mass m, connected to a rod or string of length l.
