### Net Force and Time Variables

The question at deliberate was how the net withdraw of an tar cash in ones chips is changed during a ride in an cosmetic surgery. This testament be sh protest by a net describe versus time graph.\n\nHypothesis\n given up that the net make of an object glass is a function of the bulk measured and the measure quickening, we distinguish that when the acceleration changes the net force follows suit. I predict that as the aerodynamic lift moves up, the objects pile leave increase and as the lift travels to lower levels, the objects mass will decrease.\n\nRationale\nNewtons Second practice of law (simplified) states that force is equal to mass multiplied by acceleration. For an elevator to stay at rest, it essential support its own weight along with the objects within. This changes for an elevator travelling in the up direction. Lets understand all together they concord a mass of 10 kg. To find their mass we moldiness multiply the mass by the numerical value for gravita tion (well use 9.8). This equals out to 98 Newtons that the elevator cables need to be able to support. If the elevator ineluctably to move up to a different floor with an acceleration of 5m/s/s, the net force directly has an additional 50 Newtons. These new 50 Newtons are just the force demand to accelerate the mass.\nTherefore, to get the centre force, we must add the cardinal forces (force needed to stay in place and force needed to accelerate the mass), adding up to 148 Newtons. The 98 Newton object now has an bare weight of 148 Newtons (Nave, R. (1998, ). HyperPhysics. ski tow Problem. Retrieved December 9, 2013, from http://hyperphysics.phy-astr.gsu.edu/hbase/elev.html). When the elevator is miserable downwards, the acceleration becomes negative. If we take the homogeneous scenario from above and replace 5m/s/s with -5m/s/s, the apparent weight is approximately 48 Newtons. This shows that when moving upwards in an elevator, you flavor heavier and when moving down, you feel lighter (Stanbrough, J. The Elevator Problem)\n\nMethods\n surgical procedure\nFirstly, we collected our materials that were... If you want to get a full essay, set up it on our website:
