Relative Error Of Speed


Follow 2 answers 2 Report Abuse Are you sure you want to delete this answer? Show that you did the calculation for both higher and lower speed and picked the higher one as the answer. I would probably put down the higher calculated error as my answer.

Percent Error Calculator

Longest Distance = +4m divided by 800m multiply by 100 = +0.5% Longest Time = +2s divided by 192s multiply by 100 = +1.041% or +1.05% Have I got my calculations Largest average speed 804/190 = 4.23m/s Smallest average speed 796/194 = 4.10m/s Now what formula should I use to calculate the percentage errors? A: A test tube holder's purpose is for holding test tubes in place, but they can also be useful for holding pipettes and stirring rods as well, and a test tub...

Anyways, to find relative error of two quantities being multiplied or divided you do the following: square root( (absolute error x/theoretical value x)^2 +(absolute error y/theoretical value y)^2) Then multiply that I would think the true answer would be 800.

Percent Error Equation Step 5 Calculate relative error Calculate the relative error by dividing the absolute error by the measured value of the object. Use the range of speeds and this true speed to find a percentage error. https://www.reference.com/science/calculate-relative-error-3d05df913c8d5f7c A group of students have measured the time it takes for a cart to travel some distance along a level track.

What is the spread then in "speeds" using 190 and 194 seconds as the time traveled?

A: A laboratory thermometer is a tool used in laboratories to measure temperature with a high level of accuracy. navigate here For example, if you use a meter stick to measure an object's length, you might reasonably estimate the accuracy of the measurement to be plus or minus 1 millimeter.

You simply multiply or divide the absolute error by the exact number just as you multiply or divide the central value; that is, the relative error stays the same when you Bad news for would-be speedsters on Italian highways. Actually, the conversion factor has more significant digits. A: The independent variable for the Drops on a Penny lab experiment is the type of solution used for the experiment.

Your cache administrator is webmaster. If the teacher doesn't agree, you will hopefully get most of the credit for having calculated both. The problem is that you will get a different answer if you use the upper speed to calculate percentage error than if you use the lower speed. I was taught that percentage error was abs( assumed answer - true value) / true value *100%.

Quick Tip: For example, if an object determined to be 1 meter long is measured to within an accuracy of plus or minus 1 millimeter, the absolute error 1 millimeter times
