AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Determination of Equilibrium Constants Introduction Bromothymol blue is an indicator for many acid-base titrations. When adding different solutions within the indicator it is to react and change colors‚ in this experiment the different colors were blue‚ green‚ and yellow. In the following experiment‚ obtaining the absorbance levels for each one makes it possible to calculate the equilibrium constant. Materials and Methods For this specific experiment there are a few materials that are crucial

Fawzi Abdelgani Ahmad . Experiment 1: Experimental Uncertainty (Error) and Data Analysis Jan/30/2013 PRELAB: 1. Do experimental measurements give the rule value of a physical quantity? Explain. No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

ballet dancers you think of grace and beauty. While you watch a dancer dance you never think of the physics and mathematics behind their every move. Physics is described as a thing that is all about measurement‚ and that if you know the units of measurement that physics uses and how they work you will understand everything else you’ll learn about (Dennis and Moring 1). The textbook definition of physics is “the study of matter and energy and their relationships” (Zitzewitz 1). Ballet cannot be defined

thought of all the physics that is involved in the game of golf? Golf is a game of precision and the smallest miscalculation could mess up a shot. (Real World Physics 2009) The physics of a proper golf swing is more complicated than you might think. You might think that this game is as simple as swinging a club and hitting the ball. But in fact‚ there is a lot more to it. First of all there is the importance of a good technique of coarse‚ but there is also a lot of interesting physics that goes into

CH 127 – Chem 2 Lab Determination of an Equilibrium constant Goals The purpose of this experiment is to determine the equilibrium constant for the reaction Fe3+(aq) + HSCN(aq) –>FeSCN2+(aq) + H+(aq). The equilibrium constant expression Kc for Reaction is kc=FeSCN2+[H+]Fe3++[HSCN] Procedure *Preparation of the Beer’s law plot Prepare five solutions of FeSCN2+(aq) of known concentrations between 1x10-5M and 1x10-4M by diluting various volumes of 4.62x10-4 HSCN. Calculate the Final concentration
