Experiment in Physics Lab Report Renelle L. Gapay Department of Physics Isabela State University-Ilagan Campus‚ Calamagui 2nd‚ City of Ilgan‚ Isabela Ellenergapay_23@yahoo.com Abstract In this experiment you can prove that electric charges can produce by using only a balloon and pieces of papers you can understand further static electricity and charges. And how it is produced. Introduction Have you ever wondered why rubbing a balloon make pieces of paper attract with it? The effect

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

I. Physical Features Electric eels are not really eels‚ they are actually ostariophysians‚ but have a strong physical resemblance to true eels. . An electric eel is mostly tail. The internal organs are compressed into the anterior (front) 1/5th of the body‚ and the rest of the fish consists of the long‚ electricity-producing tail. The tail contains the electric organs: Sachs’ organ‚ Hunter’s organ‚ and main organ. Extending down the entire tail region is an elongated anal fin. There are no dorsal

The Line The "line" that the film’s title refers to is the poverty line‚ or the line between "the haves and have-nots‚" as one person in the film put it. The documentary highlights the stories of four people who have found themselves on both sides of the line: a former bank vice president who lost his job‚ a Louisiana fisherman whose livelihood is threatened by environmental degradation and hurricanes‚ a former homeless man‚ and a woman that grew up in a high crime neighborhood‚ lifted herself

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
