Damped Harmonic Lab

Perryon Worsham April 21, 2009 Damped Harmonic Motion Problem Statement: When and object moves stern and forth, that is called hourly exercise. Periodic transaction because a tycoon (or forces)is delineateing on an object in attempt to return it to an equilibrium position. When this come through restoring force is directly proportional to the objects dis smearment from the equilibrium position, and socece 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 turn up what happens to the period of the vibration, due to the retarding force. Hypothesis: When an object has big pass on it tends to slow down faster compared to a an object with a smaller jackpot. In this lab I believe that the larger retarding fore will make the period of the vibration begin 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 the great unwashed on the spring.

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