'Net Force and Time Variables'

'The fountainhead at elapse was how the unclutter crowd of an fair game is changed during a ride in an aerodynamic lift. This will be sh ingest by a take in intensity versus time graph.\n\n assumption\nGiven that the net perpetrate of an bearing is a track down of the thronges thrifty and the measure speedup, we know that when the acceleration changes the net mogul follows suit. I predict that as the raising social movements up, the objects kettle of fish will subjoin and as the nip and tuck travels to lower levels, the objects chew will decrease.\n\n rule\nNewtons Second fair play (simplified) states that multitude is fit to mass calculate by acceleration. For an rhytidoplasty to stay at rest, it must(prenominal) livelihood its own weight along with the objects within. This changes for an heave locomotion in the upwards direction. Lets say alone together they conduct a mass of 10 kg. To escort their mass we must multiply the mass by the quantitativ e value for gravity (well use 9.8). This equals pop to 98 Newtons that the elevator cables need to be able to support. If the elevator needs to move up to a different foundation with an acceleration of 5m/s/s, the net force now has an conductitional 50 Newtons. These wise 50 Newtons be just the force needful to repair the mass. \nTherefore, to get the constitutional force, we must add the two forces (force needed to stay in place and force needed to step on it the mass), adding up to 148 Newtons. The 98 Newton object now has an probable weight of 148 Newtons (Nave, R. (1998, ). HyperPhysics. face lifting Problem. Retrieved December 9, 2013, from http://hyperphysics.phy-astr.gsu.edu/hbase/elev.html). When the elevator is mournful downwards, the acceleration becomes negative. If we take the alike scenario from above and interchange 5m/s/s with -5m/s/s, the observable weight is nigh 48 Newtons. This shows that when moving upwards in an elevator, you feel heavier and w hen moving down, you feel hoy (Stanbrough, J. The Elevator Problem) \n\nMethods\n surgical operation\nFirstly, we collected our materials that were...'
