FAQs on Important Questions for CBSE Class 11 (2022-23)
1. Is Class 11 Physics difficult?
Physics indeed is a difficult subject yet the most interesting one. Class 11 Physics is the starting level to introduce students to complex Physics. It takes a little time to hold a grasp of it but once understood it is very predictable. NCERT Class 11 Physics books are designed in a way that has made the learning process very interesting. At the beginning of each chapter, the concept of the actual chapter is explained in a very simple and promising manner.
2. Is Class 11 Physics NCERT important?
Yes, NCERT books are designed by the top educators of various Indian institutes, and they are designed in a way that will help the student in easy understanding of the topic without getting bored. NCERT Class 11 Physics books are produced in a way that will prepare the students for understanding the comprehensive knowledge of Physics. The books help students not only in understanding basics but also in their competitive exam preparations.
3. What is the name of Chapter 2 of Class 11 Physics?
NCERT Class 11 has two parts Physics part 1 and Physics part 2. In Physics part 1 of NCERT Class 11, the name of Chapter 2 is units and measurements, the chapter deals with learning about internationally accepted standards which are referred to as units example: kilograms (Kg). whereas physics part 2 chapter two deals with mechanical properties of fluid which explains about physical properties of gases and liquids.
4. Is the unit and measurement chapter important?
Yes, units and measurements are very important, they are important in quantification and without units and measurements it will become very difficult to quantify anything. And another most important thing is that there is a need for standard quantification rules all around the globe so that everyone follows the same rule of quantification by using the same units of measurements to avoid confusion. Earlier scientists used the CGS, FPS, MKS system of units now SI is a universally accepted system of units.
5. What are instrumental errors?
Any error which occurs due to improper making of the instrument or due to the wrong calibration of the instrument is called instrumental error. It is mainly caused due to faulty design or inaccurate calibration. For this one might take an example of weighing balance if there is any mistake happened during its production or if the balance is not properly calibrated it shows false readings during the weighing of any sample.
