Purpose: To gain knowledge about vector addition using three different methods of vector addition. Procedure: The procedure for this lab may be found in the hand out entitled “Addition of Vectors”. Analysis: x-components y-components

Results: Vector Magnitude Direction A 150 arbs 165 B 150 arbs 55 C 200 arbs 335 Resultant Vector Magnitude Direction R1 175 arbs 60 R2 135 arbs 39 R3 144 arbs 33 Conclusion: The differences between each section of this lab contained different results. The differences between part one and parts two and three were relatively large. This was expected because the graphing portion of determining vectors can have very high percentage of error. The differences between solely parts two and three was not as high, this was also expected because they are two of the more accurate ways of determining the

Unformatted text preview: resultant vector. There may have been many sources of error in each part of this lab. In the part one, error may have occurred in the use of the protractor and the ruler. Since it will not be one hundred percent accurate using the tools we were using. Yet, if more high tech tools were being used, this may have been a more accurate measurement. In part two, physical error may have been the biggest, such as not allowing the weights to have enough time to settle to achieve a proper measurement. Or environmental aspects, such as a breeze from someone walking by. In the final part, part three, the source of error is minimal, allowing this to be the most accurate measurement of the whole lab. Unless human error of using the wrong numbers, or wrong equations, may have been a factor contributing to the error for the final part....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
