Precision and Accuracy

In physics, accuracy and precision are essential terms that describe the dependability and uniformity of measurements. The degree to which a measured value resembles the true or recognized value, signifying the lack of systematic mistakes, is called accuracy. For example, to acquire an accurate result in an experiment measuring the acceleration due to gravity, the result would have to be near to the recognized value of 9.81.m/s^2 = 9.81 m/s^2/.

Contrarily, precision refers to the consistency or repeatability of measurements, independent of how near they are to the actual value. Target shooting is a famous example: hitting the bullseye repeatedly, even if it is not in the center, shows a high degree of precision. In physics, precision can be demonstrated by taking several measurements of an object’s length, each of which produces almost the same outcome. In scientific pursuits, aiming for both precision and accuracy is essential for gathering trustworthy data and coming to insightful findings.
