💡 Key Takeaways
- Distinguish accuracy from precision and why both matter in measurement results.
- Use SI units correctly and know when a unit is base or derived.
- Apply significant figures and proper rounding to report measurements.
- Read scales accurately on common measuring tools and assess measurement uncertainty.
- Identify common sources of error and basic strategies to minimize them.
❓ Frequently Asked Questions
What is the difference between precision and accuracy?
Accuracy is how close a measurement is to the true value; precision is how consistently you can repeat the measurement. You can be precise but not accurate if your results cluster away from the true value.
What are significant figures and why do they matter?
Significant figures express the precision of a measurement. They indicate which digits are meaningful and help you round results appropriately in calculations.
What are SI base units and why are they used?
SI base units are meter (length), kilogram (mass), second (time), ampere (electric current), kelvin (temperature), mole (amount), and candela (luminous intensity). They provide a universal standard for all measurements and enable consistent derived units.
How should measurement uncertainty be handled in calculations?
Report measurements with their uncertainty, and propagate it when combining values: add absolute uncertainties for sums, and combine relative uncertainties (in quadrature) for products/divisions to reflect overall precision.
