Lecture #7 || Errors and it's types | Physics 11th, chapter 1| Pcca sgl

In physics, errors refer to discrepancies between measured values and true values. These errors can arise from various sources and can be categorized into different types: Systematic Errors: These errors are consistent and repeatable, affecting measurements in the same way each time. They can result from flaws in experimental setup, calibration issues, or environmental factors. Systematic errors can lead to a bias in results, causing measurements to consistently deviate from the true value in a particular direction. Instrumental Errors: These errors stem from imperfections or limitations in the measuring instruments themselves. Examples include inaccuracies in rulers, thermometers, balances, or electronic sensors. Calibrating instruments and using appropriate measurement techniques can help minimize instrumental errors. Random Errors: Also known as statistical errors, random errors occur unpredictably and can vary in magnitude and direction with each measurement. They are often caused by factors such as fluctuations in experimental conditions, human limitations in measurement accuracy, or inherent variability in the phenomenon being studied. Random errors can be reduced through repeated measurements and statistical analysis. personal Errors: Mistakes made by the experimenter during measurement, recording, or analysis can introduce human errors. These can include misreading instruments, incorrect data entry, or miscalculations. Training, careful attention to detail, and double-checking procedures can help reduce human errors. what is error and it's types? physics class 11th chapter no 1 chapter 1 class 1st year measurements and physical quantities prime career coaching academy Sheringal physics in pashto physics with irshad pcca sgl #physicsknowledge #physics #pccasgl #physicsinpashto #Unitsandnames #physicsinpashto
