Finding Mass Using The Inertial Balance :: essays research papers

finding Mass Using the Inertial BalanceTheory Physics send packing be referred to as the study of various properties of matter and energy. Matter gage best be described by looking at the troop of an object. Mass is the amount of material that is in an object. Mass can be found by using a spring scale, a relaxation scale, or an inertial sense of equilibrium. Inertia is the resistance by mass to either change in its state of motion. Scientific Law states that mass and inertial forces are directly proportional. The purpose of the inertial balance is to invoice the opposite inertias between different masses therefore providing a mathematical and truly accurate method of measuring mass. Experimentation showed that if a mass was displace into some form of periodic motion, the mass could be measured evenhandedly accurately by measuring the oscillation period and comparing it to a known mass period. The relationship m1=m2T12/T22 was discovered.Objective After completing the expe riment, we volition be able to find the mass of objects using an inertial balance and compare them to evaluate measures. Materials C-clamps, inertial scale, a watch with a split second hand, and a triple beam balance.Procedure 1) The class willing measure the period of oscillation of their balance pans when they are empty. The accepted period will be the average of the class. To find the period, you will measure the amount of prison term it fuck offs for your balance to complete 20 oscillations. The period (T) will be computed by taking your time and dividing it by 20. This will be recorded as T2.2) You will then measure the mass of your empty pan (including entirely screws) and record this as m2.3)You will then measure the mass of unmatchable c-clamp. drop off this as m1 accepted.4)Using the inertial balance, find the time it would take for 20 oscillations of the c-clamp (which should be attached to the empty pan). Divide your time by 20 and record this as T1.5)Find the da ta-based mass of twain the c-clamp and the empty pan by using the formula from page one. Record this as mtotal.6)Find the difference between the mtotal and m2 and record this as m1experimental.7)In a utopian world, m1 experimental should equal m1 accepted.8)Find your percent shift by using the following formula% Error = (accepted-experimental) / accepted9) assume using varying amounts of c-clamps for up to three trials.DataTrial T2M2M1 acceptedT1MtotalM1 experimental1.267.9122.9.315284.12.267.9248.4.35207.91403.267.9382.45393.74275.84M1 acceptedM1 experimental% Error122.984.131.6%248.414043.6%382275.4827.88%Calculations See last page.
