How do I calculate the percentage error in the kinetic energy of a particle? You calculate the density of the block of aluminum to be 2.68 g/cm3. He found the volume to be 65 liters. And we can use Percentage Error to estimate the possible error when measuring.

This value is your 'error'.Â continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured The percentage error in measurement of time period "T"and length "L" of a simple pendulum are 0.2% and 2% respectively ,the maximum % age error in LT2 is? iitutor.com 4,170 views 10:33 FINDING VOLUME OF SOLIDS - Duration: 4:50. Lalit Mohan Sharma 1,055 views 15:38 Absolute, Relative and Percentage Errors & Uncertainty in Measurements, IIT-JEE physics classes - Duration: 4:32.

This will convert the answer into percent form. Yes No Cookies make wikiHow better. This means that you should subtract the real value from the estimated value. Steps 1 Know the formula for calculating percentage error.

Physics Lessons Math Test Ask a math question Math Search Login Calculating percent error When calculating percent error, just take the ratio of the amount of error to the accepted value Percent difference: Percent difference is used when you are comparing your result to another experimental result. Loading... When making a measurement with a micrometer, electronic balance, or an electrical meter, always check the zero reading first.

The best way to account for these sources of error is to brainstorm with your peers about all the factors that could possibly affect your result. Sign in Share More Report Need to report the video?

Answer this question Flag as... Re-zero the instrument if possible, or measure the displacement of the zero reading from the true zero and correct any measurements accordingly. Once you find the absolute value of the difference between the approximate value and exact value, all you need to do is to divide it by the exact value and multiply In most cases, a percent error or difference of less than 10% will be acceptable.

IfÂ you need to knowÂ positive or negative error, thisÂ is done by dropping the absolute value brackets in the formula.Â In most cases, absolute error is fine. We can expresss the percent error with the following formula shown below: The amount of error is a subtraction between the measured value and the accepted value Keep in mind that The term "human error" should also be avoided in error analysis discussions because it is too general to be useful. Working...
