FAQs on NCERT Solutions for Class 11 Physics Chapter 1 - Physical World
1. List Some of the Scientists and Their Major Contributions to Science.
Ans: Some of the scientists and their greatest contributions are listed in the table below:
|
|
|
Archimedes | Principle of buoyancy and Principle of Lever | Greece |
J.C. Bose | Ultra-short radio waves | India |
Albert Einstein | Theory of relativity and explanation of photo-electricity | Germany |
Michale Faraday | Law of electromagnetic induction | U. K |
2. Can Everything be Proved with the Help of Physics and Mathematics?
Ans: One should not think that all concepts can be proved with the help of Physics or mathematics. Science depends on some assumptions, which are called hypotheses, axioms, postulates, etc. A hypothesis is a supposition that does not assume it to be true. For instance, the universal law of gravitation is not something that can be proved. It can only be substantiated with experiments and observations.
3. What is the Physical World in Physics according to the Class 11 syllabus?
Ans: The first chapter in the syllabus for Class 11 Physics is called Physical World. The chapter involves topics such as the fundamental laws and principles of Science, Natural Sciences, Mathematics, and Physics. It focuses on the impact, forces, and uses of these subjects. Students will get a solid understanding of the development of various laws of Physics. All of these topics are important to grasp the basic concepts.
4. Is the Physical World important for NEET?
Ans: The chapter “Physical World” holds less importance than other chapters when one talks of NEET. It is observed that in the previous year’s question papers, not more than one or two questions are asked from this chapter. The syllabus of NEET 2024 is reduced, so the chances of this chapter’s questions are reduced. However, students should not wholly avoid studying it.
