Introduction to Significant Figures Video Lecture | Physics Class 11 - NEET

Q: 1. What are significant figures and why are they important in scientific measurements?

Ans.Significant figures are the digits in a number that contribute to its precision, including all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. They are important because they convey the accuracy of measurements and calculations, ensuring that results are reported with the appropriate level of precision.

FAQs on Introduction to Significant Figures Video Lecture - Physics Class 11 - NEET

1. What are significant figures and why are they important in scientific measurements?

2. How do I determine the number of significant figures in a given measurement?

Ans.To determine the number of significant figures in a measurement, count all non-zero digits, any zeros between them, and trailing zeros in a decimal number. Leading zeros before the first non-zero digit are not counted as significant figures.

3. What are the rules for rounding significant figures in calculations?

Ans.When rounding numbers to a specified number of significant figures, if the digit immediately following the last significant figure is less than 5, the last significant figure remains unchanged. If it is 5 or greater, you increase the last significant figure by one.

4. How do I apply significant figures in addition and subtraction?

Ans.In addition and subtraction, the result should be rounded to the least number of decimal places of any number in the calculation. This means that the final answer should reflect the precision of the least precise measurement used in the calculation.

5. Can significant figures affect the outcome of scientific experiments or calculations?

Ans.Yes, significant figures can affect the outcome of scientific experiments or calculations by conveying the precision of measurements. Using the correct number of significant figures ensures that results are not overstated or understated, which is crucial for accuracy in scientific communication and reporting.
