Setup: 'L Use a length of string to attach a block to the I0Lab. Hang the block over the edge of the table as shown while holding the IOLab in place with the wheels down. Release the |0OLab and allow it to roll at least 30 cm while the block falls. Task Using the above setup, invent a couple of ways to determine the work done by the string on the I0Lab during the first 30 cm of its motion. Measure the work done using two different methods and compare your results with uncertainty. When you compare results, make sure to discuss reasons why the results might or might not be the same. Recall that Lab Orientation shows you how to compare results that have uncertainties. Ajanta Page No. Date Using W= Fid coso . Measure the force exerted by the string ( leto say it's F = ION ) . Measure the displacement, d = 30080 = 0.30. Determine the angle between the force exerted by the string and the displacement of loLab (let's andme. it's 0= 0 as the force is applied in the direction of motion ) . ity or of all W= fid coso . FILON DON = 0.3m W = Fid cost i F LOT ( 0.3 cost Using W= change in ke Measure the initial kinetic energy of the 10 Lab (K. Einitial = OJ).Date Measure the final kinetic energy of the co lab :- let's say it's KC Exnal = toJ So AK. 8 = OK. Efinal - K.&initial to Workdone by The string is equal to The change in kinetic energy . to W = AK-E = 10J - The difference in values arises because the first method accounts for the component of the force parallel to the displacement. while the second onethed only considers the change in kinetic energy neglecting the direction of the froce .
