FAQs on Units & Measurements in One Shot (NCERT) Video Lecture - Physics Class 11 - NEET

1. What are some commonly used units of measurement?
Ans. Some commonly used units of measurement include meters for length, kilograms for weight, seconds for time, liters for volume, and degrees Celsius for temperature.
2. How do you convert units of measurement?
Ans. To convert units of measurement, you can use conversion factors. For example, to convert centimeters to meters, you can divide the value in centimeters by 100. To convert kilometers to meters, you can multiply the value in kilometers by 1000.
3. What is the difference between the metric system and the imperial system?
Ans. The metric system is a decimal-based system of measurement used internationally, which includes units like meters, grams, and liters. The imperial system, on the other hand, is primarily used in the United States and includes units like feet, pounds, and gallons. The metric system is more consistent and easier to convert between units.
4. Why is it important to use standardized units of measurement?
Ans. It is important to use standardized units of measurement to ensure consistency and accuracy in communication and comparison of data. Standardized units help in scientific research, engineering, trade, and everyday life by providing a common language for measurement.
5. What are some examples of derived units?
Ans. Derived units are obtained by combining base units. Some examples of derived units include square meters (m²) for area, cubic meters (m³) for volume, meters per second (m/s) for speed, and newtons (N) for force. These derived units are used to measure quantities that are derived from basic measurements.
