Measuring the velocity of various objects in freefall

Purpose: The purpose of this experiment was to mensurate the speed of various physical targets in freefall. Upon completion of this lab one(a) will be showcase subject to calculate the set for acceleration and the effect of personal line of credit resistance. Apparatus: 2m fix plastic tube Acculab sonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software mack information processing system with system 6.07 or later Blank 3.5 HD Macintosh formatted disk Electronic intensity scale, calipers Various objects to drop Procedure For the freshman accessory part of sample 1 we dropped three objects of the corresponding shape, just of varying good deal. To upgrade accuracy, we performed three trials for each object. The first object we dropped was a 301 guanine clump of radius 1.85 cm, followed by a 225 gram clunkock with radius 1.82 cm, and finally a 20 gram ball of radius 1.81 cm. From this information we were open to derive the down densities of the objects. mass tightfistedness = mass/((4/3)pR3 ) We recorded the germane(predicate) info and evaluated the average acceleration by means of the vend of the velocity graph.

From the following equation we primed(p) the magnitude of the scratch force out acting on the object: Force net = mass x acceleration = Force solemnity + Force air resistance Next, we calculate 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 side by side(p) part of experiment 1, we obviously conducted three trials for a pick apart pong ball of mass 20 grams and radius 1.81 cm. We followed the resembling basic use as above. Upon completion of three trials, we compared the selective information collected for the soft object with that of a heavy object. The order used in Experiment 2 is a lot... If you fate to get a practiced essay, order it on our website: Orderessay
