Systematic Error DetectionHardQuestion 30188
Question
A student consistently gets a measured value of gravity as 9.75 m/s² when the accepted value is 9.81 m/s². This is most likely due to:
- ARandom error
- BParallax error
- CSystematic error in timing or lengthCorrect
- DHuman error only
Correct answer
Systematic error in timing or length
Explanation
A consistent offset from the true value in one direction indicates a systematic error — likely miscalibrated length or stopwatch.
