Conclusion:
The purpose of this lab was to find the effect of compaction step forwardstrip of a spring on the fourth dimension of outflow for a marble and the effect of muscle contraction distance of a spring on draw of flight for a marble. The results for the compression distance versus the range of flight show a draw and quarterar, proportional kindred, with a mean of 4.8 plus or minus 3. This marrow that with ein truth centimeter added to the compression, there should be 4.8 centimeters greater distance for the flight. The best fit line doesnt encompass the origin, indeed there is systematic geological fault. For the results of compression distance verses time of flight, the relationship is strictly linear. There is no mean since it is a naiant relationship. This simply means that the time of flight is roughly the akin for every different compression distance.
Evaluation:
Our uncertainty in our slope is 62.5%, therefore the confidence in our results isnt very high. The intimately signifi arouset source of flaw was that we didnt line the device up with the beginning of the tape measure. Every time we launched the marble, our measurements were take out. This created systematic error in our data. Another major error was that we didnt do very many trials for the range of flight. This caused a large spread in our data and stochastic error.




On our graphs, there are visible outliers. They stand out and wearyt fit on our line of best fit. This can be caused by not having enough trials and all the random error from that, but the cause for the outliers hasnt been proven.
Improvement:
Our most significant source of error came from the fact that the device wasnt lined up with the beginning of the tape measure. This caused the results to be off every time we launched the marble. An improvement that can be do is to, next time, line it up so the systematic error wont be present. Secondly, we should have more trials for the range of flight. That way, the data wouldnt be as spread out and our random...If you want to get a full essay, order it on our website: Orderessay
