What factors will affect the time of a falling paper cone

What factors give print the season of a falling paper retinal coneThe issue raised is the motion of paper make cones within air as they be released. The time that the cone depart take to reach understanding level from the moment of its release depends on several variables, which pose to be investigated in order to purpose whether changing them would be relevant in affecting the period of time needed. HypothesisThere are several factors which theoretically could affect the time, assuming that the air is homogenous throughout the room and by victimisation the same paper. We have to understand that a higher or a lower top animate will be the factor which changes the time needed. Thus the factors affecting top speed will have to be investigated. These are variety, top angle, height, type of paper and tolerant forces. Some undersurface be turned out before experimentation as we know from theory that a dope difference will not affect the free falling object (it will actuall y notwithstanding to a minimum extent). ExperimentationTo investigate how different factors change the time needed one would have to set up a laboratory experiment. Immediately one encounters the first issue how far will the paper cone will have to be put in order to reach its terminal velocity? As paper cones are quite light in terms of plenteousness one can light upon that a 3 meter chute is all right, as according to Newtonian physics the lose behind on (air resistance), i.e. the upwards force will soon be equal to the weight of the paper. The aforementioned variables (top angle, resistive forces) will have to be tested by using different values. To achieve this, the experimenter will have to dig into those relationships. Size cones of different sizes but same paper will have different masses but this will not affect the time as weight is not a criterion subsequently terminal velocity has been reached. Drag coefficient the drag coefficient is a dimensionless quantity wh ich determines the aerodynamic properties of an object. The smaller it is, the lower the resistive values of fluid air. For instance for a normal cone it is of 0.5 whilst a cube has a drag coefficient (Cd) of about 1.051. The formula to find this value is Cd= Fd / 0.5V. The airs density is an uncontrollable constant whereas the mass shall be manipulated in order to see the effect. The experimenter will create three cones of different mass, let them drop off from a same height and observe. The time shall be measured. ApparatusOnly simple tools such as a scale, a stopwatch or rulers shall be used, no complicated machines such as lasers or position sensors.VariablesUncontrollable constants airs fluidityControllable variables mass, shape, aerodynamicsUncontrollable variables time plot of set upCONESCone a is the sample coneCone b is the same shape and material as A but is an scaled up version. This is done so that the effects of mass difference can be investigated. Cone c is the same s ize as A but is made of a different kind of paper, a rougher one. This is done so that the effects of the cones aerodynamics can be investigated. Cone d is of different shape than the B but has the same surface area (thus the same mass). This is done to investigate how much the steepness of the sides will affect the cone. The cone is dropped from 3 meters and simultaneously the stopwatch sets off. As it hits the earth the chronometer will have to be stopped. The figures are recorded. The process is repeated at least 5 times with all cones and thus an average is drawn. Thereafter the results are compared. The smaller the time needed, the more aerodynamic the shape is. 1 http//web.archive.org/web/20070715171817/http//aerodyn.org/Drag/tables.html
