OF EXPERIMENT The purpose of this lab was to determine the magnitude of the uncertainties produced when making measurements using common lab equipment. II.APPARATUS AND MATERIALS NEEDED safety goggles distilled water (at 20°C) laboratory apron dropper laboratory balance 2 objects of unknown mass standard masses graduated cylinder‚ 10-mL graduated cylinder‚ 100-mL III.PROCEDURE Part A: Estimating the Uncertainty of a Balance 1.We put on lab aprons and goggles. Then‚ we used the

Measurement and Uncertainty When recording data‚ each entry should be given a corresponding estimated error‚ or uncertainty. The uncertainty gives the reader an idea of the precision and accuracy of your measurements. Use the following method for finding the uncertainty associated with any measuring device used in lab. First‚ find the least count‚ or the smallest printed increment‚ of the measuring device. On the meter sticks‚ the least count is 1 mm. On the double pan balances‚ the least count

Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Abstract The success of an experiment greatly depends on how the group is able to execute it and how precise and accurate their results are. In this matter‚ errors and uncertainties in measurements are of great factor. In this experiment‚ the group was able to classify the causes of such errors and which measuring device is more precise and accurate than the other. These were obtained by measuring the diameter of an iron sphere

Gerong Department of Math and Physics College of Science‚ University of Santo Tomas España‚ Manila Abstract Measurements‚ defined as a comparison with a standard‚ are essential in the study of physics. However‚ all measurements are prone to errors. There are two sources of errors: systematic errors random errors.

Lab 1- Measurements of a Table ABSTRACT: The purpose of this experiment was to determine the value of the acceleration of a free falling object and to describe the range of experimental values. Within the experiment the items used to help provide the conclusion that 2/3 or our values fell within the 9.62m/s^2- 9.78m/s^2 range was a Vernier data-collection interface‚ Logger Pro Application and the apparatus Photogate. The results found within the 30 trial periods were all precise

Date report submitted: June 18‚ 2015 Title: Lab Techniques and Measurements PURPOSE: The purpose of this experiment is for the students to get a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure:
