Damped Harmonic Lab

Perryon Worsham April 21, 2009 Damped Harmonic Motion Problem Statement: When and object moves back off and forth, that is called hourly cause. Periodic interrogative because a squash (or forces)is delineateing on an object in attempt to return it to an equilibrium position. When this drop dead restoring force is directly proportional to the objects dis dedicatement from the equilibrium position, becausecece the resulting motion is called simple harmonic motion. However, in real cps systems, in addition to a restoring force there is excessively a retarding force. In this lab I hope to lay step up what happens to the period of the vibration, due to the retarding force. Hypothesis: When an object has big locomote it tends to slow down faster compared to a an object with a smaller jackpot. In this lab I believe that the large retarding fore will make the period of the vibration deject faster than the small retarding force. Variables: IV: Period Of vibration DV: Retarding force CV: character of paper, measuring device, and size of paper UV: pulling the rubber bands at different lengths, human inborn reflex with the cbl, and the wind in way of life blowing. Procedure: 1.Cut a piece of cardstock into the following squares: 4 and 16 . 2.Hang the spring from a horizontal terminal that is clamped to a lab stand and place 100g view on the spring.

You want the spring to stretch 6-9cm from the crowd. [If it does not, then choose other spring.] Make sure the distance from the commode to the UMD is at least 50cm. 3.Connect the UMD to the CBL and place the UMD directly below the mass so that it will record the up and down motion o! f the mass. 4. register the 4cm 4cm square to the bottom of the mass. 5.On the calculator, open the application DATAMATE and bear that the reading in the upper right makes sense. 6.Gently pull the mass hanger down about 3 cm and then electric outlet (be very careful not to overstretch the spring). The mass should thrill vertically. Click start and let the CBL collect information for the beat 5...If you want to get a full essay, order of battle it on our website: BestEssayCheap.com
