Question # 1

Name two major types of errors in measurement and also define them.

Ans 1: The major types of errors in measurement are Systematic Error and Random Error.

Systematic Errors:Systematic errors occurs when repeated measurements of a quantity give the same values under the same conditions.This error is due to poor calibration or zero error in the stop watch. This error can be removed by applying correction factor
Ans 2: Random Error: Random error occurs when repeated measurements of a quantity give different values under the same conditions. This error is due to faulty procedure or negligence and inexperience of person at the time to start or stop the stop watch. This can be reduced by taking average value of observed readings .
