Physics laboratory: solving units with two different sets of instruments

Extracts from this document...

Introduction

Physics laboratory: solving units with two different sets of instruments. Context: The following physics laboratory bases on recording and analyzing data. The principal concern this exercise has, is to measure a microscope slide with distinct varieties of instruments, and from it organize, process, and operate the data in a respective manner (in order for the end, to solve the volume and mass and thus have the desired density). A micrometer (measures to a preciseness of + 0,001cm), a vernier (measures to a preciseness of + 0,01 cm), a common ruler (measures to a preciseness of + 0,1 cm) ...read more.

has to take place. Method: The laboratory was divided onto two sections; initially were the instruments of less recording preciseness (Manual measuring balance, and a common ruler; preciseness of + 0,1 cm) and then the detailed instruments. Its Width, length, height were measured and written. From it, its percentage errors and possible errors were solved. The purpose of the percentage error is to create a discrepancy between an exact value and some approximation to it. An approximation error can happen due to main two factors which are: the measurement of the data is not precise (because of the instruments available), or also because approximations are used instead of the real data, for instance the function Pi (or mostly used as 3, 14) ...read more.

Conclusion

After having collected these measurements and placing them on a table, then began the journey onto finding the volume (with the respective percentage error, and then adding it to the percentage error the mass has and thus get the final answer for density with its final percentage error.) Finally, the result of density was given out again, but this time with its respective possible error. Following, appears all the results worked out: Table of necessary quantities for further development Table of results and materials ?? ?? ?? ?? 1 ...read more.

    Also it was very important to keep the two metal spheres constant throughout the 3 trials, and more importantly not to get them mixed with one another since the incident ball had a greater mass than the target ball. Also kept constant was the initial height of the spheres and the place where we released the incident ball from.
