Give types of errors in physics?
zero error apparatus error experimental condition experiment error parallax error
What are sources of error in principle of moments experiment?
What are some precautions and source of error in the principle of moments
If error in the measurement of momentum of a particle is 100 percent then the error in the measurement of kinetic energy is what?
p=mv %errror in p= %error in m+%error in v lowest value of m=0 hence %error in velocity=100% k.e=%error in mass=2*%error in velocity K.E=200% similarly K.Eminimun=100% total error in K.E = 100+200 =300 hence error in ke = 300%
What are Precautions and sources of error of diffraction grating experiment?
taking the measurements
If percent error in measurement of mass is 3 percent and percent error in measurement of velocity is 4 percent then what will the percentage error in measurement of kinetic energy?
Kinetic Energy = 1/2 (mass) (velocity)2Measurement of mass is in error by 3%.Measurement of velocity is in error by 4%.If both are low, then KE is measured as(True KE) x (.97) x (.96)2 = 0.894 TKE = 10.6% low.If both are high, then KE is measured as(True KE) x (1.03) x (1.04)2 = 1.114 TKE = 11.4% high.If one is high and the other low, then the net error is in between these limits.
What are the two factors affects accurate measurement?
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
Does the final temperature from the experiment equal to the final temperature from the calculation?
It should but it probably will not because of: experimental error measurement error calibration error (zero error)
What are the sources of error in the experiment calorimetry measurement?
Energy loss due to leaks in the calorimeter
What is a percent error?
It is a measure measurement of the amount of error made in an experiment. It is obtained by comparing the actual result, with the result gotten from the experiment. % error = [(experimental value - true value) / true value] x 100
What is an anova test?
An ANOVA is an analysis of the variation present in an experiment. It is a test of the hypothesis that the variation in an experiment is no greater than that due to normal variation of individuals' characteristics and error in their measurement.
The standard error of measurement is always zero when the reliability coefficient equals what number?
.00
Which property of a measurement is best estimated from the percent error?
Measurement error: obviously!
Why are several trials taken for each measurement in an experiment?
A good way to reduce error or increase measurement accuracy is to take several measurements and compute their average. In other words, you achieve accuracy through averaging. (This also validates the repeatability of the measurement.)
If a measurement is small is the percentage error high?
yes, it is. The smaller the measurement, the higher the percentage error.
What is error analysis?
the precentage of error in data or an experiment
How do you overcome or reduce the problem of random error and systematic error while doing an experiment?
how to reduce the problem of random error and systematic error while doing an experiment
What is an error in measurement?
A error in measurement is when the measurement taken is not actually correct. For instance, you measure a gap as 49 centimetres wide. You cut the plank of wood to fit that measurement. Then discover the wood you have just cut is too wide to neatly fit the gap. There has been an error in the measurement you have taken.
