Quite simply the analysis is everything that you do between data collection and the writing of the conclusion. Friction of the falling bob against the sparking wire slowed it down, meaning that the distance intervals that we measured are shorter than what they should have been.

If you’re the one who is always having hard times when writing a lab report. 0046 145. This activity is an introduction to physics laboratory investigations. The voltages as measured for the pressure and temperature transducers appear in Table A-1 of the Appendix. Temperature versus pressure, as calculated from the ideal gas equation. Submitted by Chad Orzel, Physics Department, Union College.

Remember that no experiment is 100% precise, because all measurements – made by humans or electronic data gathering tools – are imprecise to some limit. The uncertainty associated with the average C/D ratio is the standard error of the five C/D values, which is equal to the standard deviation (0. Both of these transducers produced voltage signals (in Volts) that were calibrated to the pressure (kPa) and temperature (K) of the air (the atmospheric pressure for where the experiment occurred is assumed to be 13. Be sure to add a sentence or two as to whether or not you believe the amount of observed random error impacted the results and if so, HOW the results were impacted (i. Make the lab instructor believe that you understand.

Guidelines for a Physics Lab Reports. ” )   Note that you should include in your results an estimate of the uncertainty of your calculations and experiment. 11 for this same ratio. The larger uncertainty from the graphical analysis suggests that the random measurement errors may be larger than estimated in the numerical analysis. As a guide, address the following questions in your conclusion. 0011 99.

In essence this is a list of equations, but it goes one step further as it shows one example of every equation being used. 0107 184. This is where all of the science is. 0073 152. Differences existed in the experimental graph of temperature versus and pressure and the theoretical curve of temperature versus pressure. In longer and more complex experiments, you would include results of prior relevant research, too. A few letters can make a big difference in a scientific term. The diameter of each of the 5 objects was measured with either the ruler or caliper. Remember this is the meat of your report.     Relative to the claim just stated, now focus the readers’ attention on the evidence that supports the claims.

This is the punch line of this huge and massive joke-it needs to be good. From this final column arose Figure A-2, a graph of ideal temperature (K) versus pressure (kPa). In this calculation, which used the ideal gas equation, the volume and mass were assumed to be constant. 0020 102. 03 Figure A-1. 69 8. Finally, column 5 presents the ideal values of temperature for the corresponding measured values of pressure. 0073 152.

0064 147. In the equation, pV = mRT, where p is the pressure the gas, V is the volume, m is the mass, R is a constant, and T is temperature. 17 6. 0114 187. As shown in this graph, the relationship between temperature and pressure is exactly linear.

Graphical analysis lead to a less precise but equivalent estimate of 3. The objective of the experiment is to test whether the ideal equation of state holds. Because the ideal gas was in a closed container, its volume remained constant.   If you don’t know what your major will be, use the IEEE standards for citations, as I’ve shared in my online guide. DO NOT copy the procedure from the book or lab manual. “We found the acceleration of gravity to be g = 9.

Write the procedure in your own words and add notes and diagrams as necessary. Given that the temperature and pressure ranges are large, the calibration equations between the voltage signals and the actual temperatures and pressures might not be precise for that entire range. Introduction – describes the experiment, and why it was important. Column three shows the measured values of pressures calculated from the following calibration curve for the pressure transducer: p = 4. Several errors could explain the differences: precision errors in the pressure transducer and the thermocouple; bias errors in the calibration curve for the pressure transducer and the thermocouple; and imprecision in the atmospheric pressure assumed for the locale. Show schematic of experimental setup where necessary. Differences existed in the experimental graph of temperature versus and pressure and the theoretical curve of temperature versus pressure.

These theoretical values of temperature are shown in the final column of Table A-1. As a guide, address the following questions in your conclusion. 75 8. Interpretations should be supported whenever possible by references to the lab handout, your text, and/or other studies from the literature that can be properly cited. For many labs in your Physics classes at Chabot College, you’ll be asked to create a formal lab report. Figure A-2 shows the graph of temperature versus pressure for the ideal case.

The uncertainty in the measurements could be due to the paper-wrapping method of measuring the circumference, circles that may not be perfect, and the limited precision of the measuring devices. 69 8. Several errors could explain the differences: precision errors in the pressure transducer and the thermocouple; bias errors in the calibration curve for the pressure transducer and the thermocouple; and imprecision in the atmospheric pressure assumed for the locale. Do not assume that science (or an essay topic) is too complicated for you to understand. The first two columns of Table A-1 show the measured voltages from the pressure transducer and the temperature transducer. If changes are made in the lab record them, if certain elements of the lab are not performed record the differences, or if you use a particular piece of equipment that is unique, make note of it.

In this investigation, we examined the hypothesis that the circumference (C) and diameter (D) of a circle are directly proportional
