Purpose: The purpose of this experiment was to measure the velocity of confused objects in freefall. Upon completion of this lab one will be suit subject to calculate the values for speedup and the picture of wrinkle resistance. Apparatus: 2m fix plastic tube Acculab transonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software Macintosh computer with system 6.07 or later asinine 3.5 HD Macintosh formatted disk Electronic intensity scale, calipers Various objects to flatten Procedure For the first gear part of sample 1 we dropped cardinal objects of the corresponding shape, but of varying good deal. To resurrect accuracy, we performed three trials for each object. The first object we dropped was a 301 gibibyte clump of rundle 1.85 cm, followed by a 225 gram clunk with radius 1.82 cm, and finally a 20 gram screwball of radius 1.81 cm. From this information we were able to derive the masses densities of the objects. mass density = mass/((4/3)pR3 ) We recorded the germane(predicate) data and evaluated the average quickening 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 cypher 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 completion o f three trials, we compared the data collect! ed for the soft object with that of a impenetrable object. The method used in Experiment 2 is a lot... If you want to get a full essay, order it on our website:
