am using the equation v^2 = 2as but im confused as how to calculate the error for velocity. Do I just add the errors of acceleration (gravity) and distance together? Or is there another way? any help or suggestions of websites would be really great! thanks Update: sorry i should have mentioned earlier, but the error of gravity is quite insignificant so does this affect it?

Edit: That is, if the errors are relative errors. If the errors are absolute, then you have to convert to relative. For example: 25 +/- 5 mph, the absolute error is 5 mph. The relative error is 5/25 X 100, or 20% Expressed in relative error, 25 +/- 5 mph is 25 mph +/- 20% Source(s): AntiApollyon · 7 years ago 2 Thumbs up 0 Thumbs down Comment Add a comment Submit · just now Asker's rating Report Abuse Add your answ

The formula is given by: The experimental value is your calculated value, http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ 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 speed of light is almost 299,800 km/s. What was the percent error of Rømer's estimate?Solution:experimental value = 220,000 km/s = 2.2 x 108 m/stheoretical value = 299,800 km/s 2.998 x 108 m/s So Rømer was quite a bit off by our standards today, but considering he came up with this estimate at a time when a majority o

I estimate velocity using Velocity = (PosA how to calculate - PosB)/DeltaT I am trying to estimate the error in my velocity estimate, but I can't seem to find any ways to calculate this. I assume it has to use Sigma_PosA and Sigma_PosB. I would also assume it's relative to DeltaT and/or abs(PosA - PosB). What is the velocity measurement variance/standard deviation? algorithms statistics share|cite|improve this question edited Sep 1 '11 at 5:17 Mike Spivey 36.3k6108198 asked Aug 31 '11 at 21:22 Charles L. 1085 migrated from stackoverflow.com Aug 31 '11 at 22:09 This question came from our site for professional and enthusiast programmers. What do you know about the error in the two positions? Do you have an explicit distribution, or just an error term? –templatetypedef Aug 31 '11 at 21:23 Are the errors in the positions measurements uncorrelated?

A person travels 800m +/-4m in a time of 3 minutes 12 seconds +/-2sec I have to work out the largest and smallest possible values for the speed along with the percentage error for the speed and distance travelled. 2. Relevant equations = Distance/Time = Speed 3. The attempt at a solution This is were I get myself in a muddle I am not sure if I should add +/-4m to 800m to make it 804m and 796m or should it be 798m and 802m = +/-4m (like wise with the time) If someone could explain the correct steps in solving this problem that would be great. 1.
