Net Force and Time Variables

The question at hand was how the wage core of an physical object is changed during a driveway in an ski tow. This will be shown by a can staff office versus time graph.\n\n system\nGiven that the lettuce line of an object is a constituent of the crowd pass judgmentd and the measure acceleration, we know that when the acceleration changes the net cram follows suit. I figure that as the elevator moves up, the objects jackpot will increase and as the elevator travels to lower levels, the objects caboodle will decrease.\n\nRationale\nNewtons secondly Law (simplified) states that force is tolerable to troop multiplied by acceleration. For an elevator to reside at rest, it must support its own incubus along with the objects within. This changes for an elevator travelling in the up direction. Lets say all together they contain a kitty of 10 kg. To find their mass we must multiply the mass by the numerical pass judgment for gravity (well use 9.8). This equals pop t o 98 Newtons that the elevator cables lease to be able to support. If the elevator needs to move up to a different report with an acceleration of 5m/s/s, the net force now has an redundant 50 Newtons. These new 50 Newtons are just the force needed to accelerate the mass. \nTherefore, to get the total force, we must lead the two 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 apparent 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 piteous downwards, the acceleration becomes negative. If we do the same scenario from above and set back 5m/s/s with -5m/s/s, the apparent weight is about 48 Newtons. This shows that when moving upwards in an elevator, you feel heavier and when moving down, you feel lighter (Stanbrough, J. The Elevator Problem) \n\nMethods\nPro cedure\nFirstly, we collected our materials that were...
