WebThe precession angular velocity is ωP = dφ dt ω P = d φ d t and from this equation we see that. ωP = rMg Iω. ω P = r M g I ω. In this derivation, we assumed that ωP ≪ ω, ω P ≪ ω, that is, that the precession angular velocity is much less than the angular velocity of the gyroscope disk. WebNov 13, 2015 · Precision is too often confused with Accuracy and many consider those two words as synonyms. However, precision has absolutely nothing to do with accuracy, ... WebThe concepts of accuracy and precision are almost related, and it is easy to get confused. Precision is a number that shows an amount of the information digits and it expresses the value of the number. For Example- The appropriate value of pi is 3.14 and its accurate approximation.
