Compound pendulum lab report n the flame test could potentially have been contaminated by using the same nichrome wire over and over for different compounds. Results: report your results for the values of n, k, and g (in complete sentences) make sure all values are properly rounded and have the correct number of significant digits.
The period of a pendulum is give approximately by the formula t = 2pisqrt(l/g) where l is the length of the pendulum and g is the acceleration (not accerlation) due to grav ity thus g is. Experiment 10: compound pendulum object : to study the properties of a compound pendulum, and to determine the acceleration due to gravity by the use of such a pendulum method : an experimental pendulum is suspended successively about several axes at different points along its length and the period about each axis is observed. A compound pendulum should be the one that is made of several metal rods of different materials - like brass for some rods and steel for others - that act against each other to keep the length the same as the temperature changes, thus the time more accurate (the brass expands up more than the steel does down.
Sample formal laboratory report for phys 131 2 introduction† a compound pendulum is a rigid body swinging in a vertical plane about any horizontal axis passing through the body. With a simple pendulum quintin t nethercott and m evelynn walton department of physics, university of utah, salt lake city, 84112, ut, usa respect to the lab. Pendulum in different medium rural corselets oasis introduction an oscillating object is a mass that follows a pattern that causes the mass to return to its initial position after completing one complete oscillation in a constant certain amount of time. Compound pendulum page 2 of 5 figure 1: generalized pendulum the parallel axis theorem states that i o = i g + mh 2 1 where i g is the moment of inertia about a parallel axis through the center of mass, so that.
A pendulum is a weight suspended from a pivot so that it can swing freely when a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. Compound pendulum lab report of oscillation of a simple pendulum with verify 3 types of different specimens 2) to determine the center of gravity of a. Lab report compound pendulum in different medium lab report compound pendulum in different medium raoul corstjens is10a introduction an oscillating object is a mass that follows a pattern that causes the mass to return to its initial position after completing one complete oscillation in a constant certain amount of time.
A compound pendulum is a pendulum consisting of a single rigid body rotating around a ﬁxed axis in contrast to the simple pendulum we studied in class, a compound pendulum can have an arbitrary. Pendulum depends on the distance between the point of suspension and the center of mass the compound pendulum you will use in this experiment is a one metre long bar of steel which may be supported at different points along its length, as shown in fig 1. The same pendulum bob was used - interchanging the pendulum bob would have resulted in a differentmomentum of the pendulum for each different trial, as well as and alternation in acceleration due to the changein mass3. Pendulum lab 203 - phet interactive simulations. First year physics laboratory (p141) manual list of experiments 2015-16 1 measurement of 'g' using compound pendulum 2 measurement of moment of inertia of different bodies and proof of parallel.
So we used the compound pendulum to determine the acceleration due to gravity in the lab, called the bar pendulum theory a bar pendulum is the simplest form of compound pendulum it is in the form of a rectangular bar (with its length much larger than the breadth and the thickness) with holes (for fixing the knife edges) drilled along its. Lab report compound pendulum in different medium raoul corstjens is10a introduction an oscillating object is a mass that follows a pattern that causes the mass to return to its initial position after completing one complete oscillation in a constant certain amount of time. Performing the real lab: the compound bar pendulum ab is suspended by passing a knife edge through the first hole at the end a the pendulum is pulled aside through a small angle and released, whereupon it oscillates in a vertical plane with a small amplitude.
This is an example of a lab report associated with obtaining the acceleration due to gravity (g) and applying mathematical models this example serves as a template to assist you in writing lab reports for. The main difference between simple pendulum and compound pendulum is that, in a simple pendulum, the distance between the centre of gravity of the suspended body and the axis of suspension is large compared to the dimensions of the suspended body whereas, in a compound pendulum, the dimensions of the suspended body are comparable to the. Ding 2 i will be investigating the effect of the length of a pendulum's string on the time for the period of that pendulum given my previous knowledge, i know that a pendulum behaves in an. 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 another factor involved in the period of motion is, the acceleration due to gravity ( g ).
