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

Percentage Error is the absolute value of the difference of the Theoretical value and Experimental value all over the Theoretical Value multiplied to 100. It is used to compare the results obtained to the known or accepted value. METHODOLOGY I. Materials 50-mL graduated cylinder 125-mL flask Electronic

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

The Physics 500 Introduction: The purpose of this lab is to show how to calculate the average speed and acceleration in six different races. In order to find average speed you will need to use the formula s=d/t (s= speed‚ d=distance‚ t=time). On the other hand‚ for accelaration you will use the formula a= vf-vi/t (a=acceleration‚ vf=final velocity‚ vi= initial velocity‚ t=time). Average speed is how fast something is moving; the path distanced moved per time. Acceleration is the
