Which reading is more accurate, mass or length? Give a reason for your answer.
Understand the Problem
The question is asking for a comparison of the accuracy of mass and length measurements, along with a justification for the choice made. It involves scientific reasoning about measurement accuracy.
Answer
Mass is more accurate than length.
The mass measurement is generally more accurate. This is because scales are often calibrated to high precision and aren't significantly affected by environmental factors. Length measurements can be less accurate due to human error and limitations in the precision of measuring tools.
Answer for screen readers
The mass measurement is generally more accurate. This is because scales are often calibrated to high precision and aren't significantly affected by environmental factors. Length measurements can be less accurate due to human error and limitations in the precision of measuring tools.
More Information
Mass measurements tend to be more precise because scales are designed to detect small differences accurately, whereas measuring length can involve more error due to the need for precise alignment and subjective reading of measurement marks.
Tips
A common mistake is not considering the precision of the tools or human error in reading measurements.
