Pendulum Lab Write-up

Pendulum Lab Write-up         Going into the lab, we were told that the two things that gear up the appearance a pendulum works was the length of the pendulum. Weight and angle of upside didnt effect the way the pendulum acted. From this information, my teammates and I came up with a mesa to equal how the length of the pendulum (in meters) was related to the flow rate of the swings. ( flowing= seconds/swings). afterward we got a matter of value in our table, we proceeded to graphical track record the values in x, y format i.e.: the Period became the x coordinates and the length became the y coordinate. The resulting graph looked parabolic. With this information, we now knew what the basic pattern for determining the relationship of duration and Period had to be f (x)= x^2. We nagged in one of the sets from kayoed table and came up with the two sides not equaling each other. Now since the vertex had to be (0,0), because a pendulum length of 0 would m ean there is no pendulum, we didnt have to gravel ab come forth translations of the graph; however, since the basic figure y=x^2 didnt work, the only possible consequence was to multiply the pointedness by some invariant. We named this constant M. Since the period equateed the x and the length represented the y, we simply substituted in our cause variables and came up with the formula Length = (M*Period)^2. To find M, all we had to do was plug in one of our sets of values from our table and solve. M came out to be .48; and so the final formula came out to be Length = (.48 * Period)^2. 1. Make a table of values analyze the Length of the Pendulum and the period. 2. Graph the values using Period to represent x and Length to represent y 3. guess the yield function and plug in numbers 4. welcome the constant M and substitute in all variables raillery/ epitome         The main source of error is the fact that the roller coaster train dejection be stretc hed so it is confusing defy to make the str! ing as taut or retain it loose. Also, there is a lot of human error that occurs when quantify the swings. The time it takes for our look and minds to realize the string has started to swing wasnt deducted from the computations. Ideas for gain applications         This lab could be used to find the height of a school building, or a poster! If you want to bring on a broad essay, order it on our website: BestEssayCheap.com
