The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon was due to the fact that the speed of light was finite, and subsequently estimated its velocity to be approximately 220,000 km/s. The current accepted value of the

How To Calculate Experimental Error Physics
Post Share By Anne Marie Helmenstine, Ph.D. Updated August 13, 2015. Error is a measure of the accuracy of the values in your experiment. It is important to be able to calculate experimental error, but http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ there is more than one way to calculate and express it. Here are the most common ways to calculate experimental error:Error FormulaIn general, error is the difference between an accepted or theoretical value and an experimental value.Error = Experimental Value - Known ValueRelative Error FormulaRelative Error = Error / Known ValuePercent Error Formula% Error = Relative Error x 100%Example Error CalculationsLet's say a researcher measures the mass of a sample to be http://chemistry.about.com/od/chemistryquickreview/a/experror.htm 5.51 g. The actual mass of the sample is known to be 5.80 g. Calculate the error of the measurement.Experimental Value = 5.51 gKnown Value = 5.80 gError = Experimental Value - Known ValueError = 5.51 g - 5.80 gError = - 0.29 gRelative Error = Error / Known ValueRelative Error = - 0.29 g / 5.80 gRelative Error = - 0.050% Error = Relative Error x 100%% Error = - 0.050 x 100%% Error = - 5.0% Show Full Article Related This Is How To Calculate Percent Error Percent Error Definition See How To Calculate Absolute and Relative Error A Quick Review of Accuracy and Precision More from the Web Powered By ZergNet Sign Up for Our Free Newsletters Thanks, You're in!
