The purpose of this lab was to find the effect of compression distance of a spring on the time of flight for a marble and the effect of compression distance of a spring on range of flight for a marble. The results for the compression distance versus the range of flight show a linear, proportional relationship, with a mean of 4.8 plus or minus 3. This means that with every centimeter added to the compression, there should be 4.8 centimeters greater distance for the flight. The best fit line doesn’t encompass the origin, therefore there is systematic error. For the results of compression distance verses time of flight, the relationship is strictly linear. There is no mean since it is a horizontal relationship. This simply means that the time of flight is roughly the same for every different compression distance.
Our uncertainty in our slope is 62.5%, therefore the confidence in our results isn’t very high. The most significant source of error was that we didn’t line the device up with the beginning of the tape measure. Every time we launched the marble, our measurements were off. This created systematic error in our data. Another major error was that we didn’t do very many trials for the range of flight. This caused a large spread in our data and random error.
On our graphs, there are visible outliers. They stand out and don’t 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 hasn’t been proven.
Our most significant source of error came from the fact that the device wasn’t 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 made is to, next time, line it up so the systematic error won’t be present. Secondly, we should have more trials for the range of flight. That way, the data wouldn’t be as spread out and our random...
