The force and the acceleration did changed as the car moves along the track of the launching ramp and also, they are affected by position of the load cell, but the data shown by Sparkvue is unexpected. We assume that the force and the resultant will be the highest as the car moves from the top to the bottom; however, according to the tables and the graphs, as the load cell is placed farther from the starting point, the acceleration will experiment more severe fluctuation.  When the load cell is attached to the longest supporting beam(position 1), according to graphs 1.1,1.2 and1.3, the acceleration fluctuated between 9.7 and 10.0m/s2 while the force is more constant than the acceleration but it also shows  volatility. When the load cell is attached to the beam that’s connecting the no.1 beam and the no.4 beam,the acceleration(resultant acceleration remains constant but acceleration-x,y,z show changes) will experience strong fluctuation at the beginning, but it will become more constant as the car continues with its journey. The force remains constant despite of some slight fluctuation from the beginning to the end.  When the load cell is attached to the place that’s farther from the starting point, both acceleration and force present strong fluctuation, with the strongest at the beginning.
