Lab 5 Gravitational AccelerationPreparation In supplying for the first part of this lab involving the Atwoods machine our team started by discussing the make of the crowd together on the results of the machine as requested in nous 1 of the lab manual. We conceive that if the two citizenryes were equal thither would be no motion of either of them when released. However we believed that if the two lower classes were not equal, the heavier mass would fall downward pulling the lighter mass upwards. Below as requested by misgiving 2 is a free body diagram of both(prenominal) situations crowd EqualMasses UnequalThe tensity on mass 1 is equal to the tension in mass 2 due to the same string attaching both masses and is shown mathematically above in the section where the masses atomic number 18 equal. In the second part gravity is solved for.We also believe that the difference between the two masses will affect the speedup in a linear matter as requested in question 3. In prepara tion for part 2 we started by answer question 4 on which graph best describes freefall based for outdo vs. time. We believed graph (b) showed this and is shown below.Our able for this was that the object in free fall is undergoing a unvarying acceleration meaning its velocity will increase with time. This is shown on graph (b) by the increasing heel over with time, and is the only graph to commence its slope increase with time. graphical record (a) has constant slope and graph (c) has its slope decrease with time. For question 5 which asked for the best velocity vs. time graph we believed that graph (a) is the best graph.Our rational for this was that because the object is under constant acceleration the velocity will increase at a constant rate. Graph (a) shows this while graph (b) shows constant velocity and graph (c) shows decreasing velocity. For question 6 which asked for the best acceleration vs. time graph we believed that graph (b) shows this the best. Our rational fo r this was that the object is under constant acceleration. Only graph (b) shows a constant acceleration. Graph (a) shows decreasing acceleration while graph (c) shows increasing acceleration. process Our procedure for part 1 is the following First we measured the masses of both sides of the Atwoods machine and record these values. Next we held the smaller mass on the ground and measured the distance from the ground to the bottom of the larger mass, affair this value "s".
