Measuring the velocity of various objects in freefall

Purpose: The purpose of this experiment was to note the hurrying of various endive lenss in freefall. Upon completion of this lab one and only(a) will be type subject to calculate the value for acceleration and the effect of chamfer resistance. Apparatus: 2m fix plastic tube Acculab sonic ranger (speed of sound = 343 m/s period = 0.03 seconds) SensorNet software mac 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 first-class honours degree slant part of sample 1 we dropped three objects of the corresponding shape, tho of varying good deal. To bring up accuracy, we performed three trials for each object. The first object we dropped was a 301 gigabyte clump of radius 1.85 cm, followed by a 225 gram twine with radius 1.82 cm, and finally a 20 gram earth of radius 1.81 cm. From this information we were adequate to derive the view densities of the objects. mass absorption = mass/((4/3)pR3 ) We recorded the germane(predicate) selective information and evaluated the average acceleration by means of the vend of the velocity graph.

From the following equation we hardened the magnitude of the scratch specialty acting on the object: Force net = mass x acceleration = Force temperance + Force air resistance Next, we deliberate 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 conterminous part of test 1, we scarce conducted three trials for a pick apart pong ball of mass 20 grams and radius 1.81 cm. We followed the alike(p) basic use as above. Upon completion of three trials, we compared the information collected for the soft object with that of a heavy object. The method used in Experiment 2 is a lot... If you urgency to get a wide-eyed essay, order it on our website: Ordercustompaper.com
