Relationship Between Drop Height and Diameter of Plasticine Sphere Essay

PROBLEM A student suggest that there is a proportional relationship between flush at which a plasticine plain is overtopped and the diam of the flattened part after cliffping. Design an experiment to determine if this innuendo is true or not. AIMTo investigate the relationship between the drop height and the flattened part of a plasticine field of operations after beingness dropped.HYPOTHESIS As the height of the orbital cavity plasticine increases the dia criterion increases.VARIABLESManipulating The drop height of the sphere plasticineResponding The dia standard of the flattened part of the sphere. Controlled The size of the ball, the surface battlefield of the drop height and the material from which the sphere is made. APPARATUS Sphere plasticine, meter ruler, Vernier caliper, railroad train, re watcher METHODMake a sphere place of plasticine and measure its size employ the Vernier caliper to maintain a constant size throughout the experiment. Get a flat and refine surface area.Use a meter ruler to measure 60m supra the surface area and stand up the plasticine to the ruler at the 60m and drop it. wander a piece of string well-nigh the flattened part of the sphere and single-valued function a marker to mark off where the string stops. pulse the aloofness of the string up to where the mark stops using a meter ruler. Divide the length of the string by 3.14 (pi) to get the diam. take the drop height and the diameter of the sphere in a table. thread the plasticine back into a sphere using the measurements from the Vernier caliper. Measure 40m in a higher place the surface area using a meter ruler and hold the plasticine to the ruler and drop it from that height.Wrap a piece of string around the flattened part of the sphere and use a marker to mark off where the string stops. Measure the length of the string up to where the mark stops using a meter ruler. Divide the length of the string by 3.14 (pi) to get the diameter. Record the drop heig ht and the diameter of the sphere in a table. Roll the plasticine back into a sphere using the measurements from the Vernier caliper. Measure 20m above the surface area using a meter ruler and hold the plasticine to the ruler and drop it fromthat height. Wrap a piece of string around the flattened part of the sphere and use a marker to mark off where the string stops. Measure the length of the string up to where the mark stops using a meter ruler. Divide the length of the string by 3.14 (pi) to get the diameter. Record the drop height and the diameter of the sphere in a table. EXPECTED RESULTSThe sphere that has a drop height of 60m should have a larger diameter than the sphere with a drop height of 40m and 20m. The results should be recorded in a table. HeightDiameterDATA ANALYSISThe height at which the sphere plasticine is dropped and the diameter are directly proportional therefore as the height increases so should the diameter. If the sphere dropped at 60m has a larger diameter than the sphere dropped at 40m or 20m consequently the hypothesis is accepted. If the sphere dropped at 20m has a larger diameter than the sphere dropped at 40m or 60m then the hypothesis is rejected. SOURCES OF ERRORS / PRECAUTIONSA source of error is parallax error and a maintenance to take to prevent this error is to do readings more than once, record them and discover the average. Another source of error is not reading the Vernier collection plate on the Vernier caliper from the zero mark a tending to take is to make sure that you start reading the Vernier get over from the zero mark.
