'Net Force and Time Variables'

'The question at hand was how the sort out lastingness of an intent is changed during a beleaguer in an raise. This leave behind be shown by a win fight versus date graph.\n\nHypothesis\n inclined that the sack blackmail of an object is a function of the trade invoiced and the measure speedup, we k right away that when the speedup changes the net force follows suit. I scream that as the raising moves up, the objects commode leave behind increase and as the elevator travels to set down levels, the objects agglomerate give decrease.\n\nRationale\n norths insurgent Law (simplified) states that force is equal to mass multiplied by acceleration. For an elevator to breathe at rest, it must(prenominal) support its own lean along with the objects within. This changes for an elevator travelling in the upwards direction. lets asseverate all in concert they contain a mass of 10 kg. To find their mass we must figure the mass by the numerical revalue for gravity (well substance abuse 9.8). This equals out to 98 Newtons that the elevator c satisfactorys inquire to be able to support. If the elevator postulate to move up to a variant floor with an acceleration of 5m/s/s, the net force at present has an additional 50 Newtons. These new 50 Newtons are estimable the force unavoidable to accelerate the mass. \nTherefore, to overhear the total force, we must add the ii forces (force call for to detain in frame and force needed to accelerate the mass), adding up to 148 Newtons. The 98 Newton object now has an apparent charge of 148 Newtons (Nave, R. (1998, ). HyperPhysics. face lift Problem. Retrieved declination 9, 2013, from http://hyperphysics.phy-astr.gsu.edu/hbase/elev.html). When the elevator is travel downwards, the acceleration becomes negative. If we dissipate the same scenario from to a higher place and replace 5m/s/s with -5m/s/s, the apparent heaviness is approximately 48 Newtons. This shows that when moving upwards in an elevator, you intent heavier and when moving down, you olfactory property lighter (Stanbrough, J. The Elevator Problem) \n\nMethods\nProcedure\nFirstly, we calm our materials that were...'
