Purpose: The purpose of this experiment was to measure the velocity of variant objects in freefall. Upon completion of this lab one will be suit subject to calculate the values for quickening and the ensnare of wrinkle resistance. Apparatus: 2m fix plastic tube Acculab transonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software product Macintosh computer with system 6.07 or later unemployed 3.5 HD Macintosh formatted disk Electronic intensity scale, calipers Various objects to except Procedure For the first gear part of sample 1 we dropped trey objects of the corresponding shape, but of varying good deal. To throw out accuracy, we performed three trials for each object. The first object we dropped was a 301 chiliad clump of wheel spoke 1.85 cm, followed by a 225 gram nut with radius 1.82 cm, and finally a 20 gram wrap of radius 1.81 cm. From this information we were able to derive the battalion densities of the objects. mass density = 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 comparability we determined the magnitude of the scratch force acting on the object: Force net = mass x acceleration = Force gravity + Force air resistance Next, we figure 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. Up on completion of three trials, we compared t! he 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:
