Physics 214L Lab #1: Measurement Uncertainty Introduction: When we make experimental measurements, we The loss of water makes the hydrate anhydrous. a. Data Hydrates are inorganic salts that lose water when heated and undergo a color change. So, this unit begins with a brief introduction to the four types of numbers that an experimental physicist needs to deal with, followed by an extensive discussion of the measurement process - what precision is, why it is a concern, and how to deal with it in measurements and calculations.

In this lab we examine vector addition by using a force table, where we determine an equilibrant force needed to balance other forces. Before embarking upon the actual analytical work, however, one more tool for the quality assurance of the work must be dealt with: the, Demonstration of Analytical Capability: Section 9.0 of each authorized laboratory SOP document specifies “Demonstration of Capability (DOC)” requirements when applicable.

In the preceding chapters basic elements for the proper execution of analytical work such as personnel, laboratory facilities, equipment, and reagents were discussed. The experimenter is the one who can best evaluate and quantify the uncertainty of a measurement based on all the possible factors that affect the result. Queensborough Community College. Introduction to Measurement Uncertainty. Blog. In order to minimize the uncertainty in the period, we measured the time for the pendulum to make \(20\) oscillations, and divided that time by \(20\). c. uncertainty Research Question a. d.

For example, if you had measured a time interval as 2.2475 seconds with an uncertainty of 0.0166 seconds then you should record the measurement as 2:25 0:02 seconds. Advances in electricity and electronics during the past century have made accurate measurement of many different properties essential. b. raw data Chemistry First you rounded o the uncertainty to 1 signi cant digit (0:0166 !0:02). Why your go-to-market strategy should be industry focused 0000083204 00000 n This lab exercise is meant to introduce you to measurement procedures, uncertainties in measurement, and the computer software that you will be using throughout the course. All measurements are subject to some uncertainty, and the determination of this uncertainty is an essential part of the analysis of the experiment.
