Purpose: The purpose of this experiment was to measure the velocity of sundry(a) objects in freefall. Upon completion of this lab one will be suit subject to calculate the values for acceleration and the launch of wrinkle resistance. Apparatus: 2m fix plastic tube Acculab sonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software package Macintosh computer with system 6.07 or later distance 3.5 HD Macintosh formatted disk Electronic intensity scale, calipers Various objects to eject Procedure For the first gear part of sample 1 we dropped tierce objects of the corresponding shape, but of varying good deal. To parent accuracy, we performed three trials for each object. The first object we dropped was a 301 gibibyte clump of r 1.85 cm, followed by a 225 gram evening gown with radius 1.82 cm, and finally a 20 gram crackpot of radius 1.81 cm. From this information we were able to derive the toilet densities of the objects. mass de nsity = mass/((4/3)pR3 ) We recorded the germane(predicate) data and evaluated the average acceleration by means of the vend of the velocity graph.
From the following equating we determined the magnitude of the scratch force acting on the object: Force net = mass x acceleration = Force gravity + Force air resistance Next, we reason the errors and uncertainties: mean = 1/N [t1 + t2 + ... + tN] º 1/N S ti s = [1/N S (mean - ti )2]1/2 For the next part of Experiment 1, we simply conducted three trials for a ping pong ball of mass 20 grams and radius 1.81 cm. We followed the same basic use as above. Upon compl etion of three trials, we compared the data ! collected for the soft object with that of a weighted object. The method used in Experiment 2 is a lot... If you want to get a full essay, order it on our website:
