Book Description:
Physics is one of the most fundamental of all sciences, which deals with nature and various phenomena related to day-to-day life. This makes physics quite interesting and enjoyable subject. Ninth class is an important preparatory platform where students learn concepts and laws of physics which are used in higher classes as well as in competitive examinations. Considering this, related concepts which would be taught in higher classes are given in this book.
This book starts every topic at an elementary level. Concepts and definitions are presented in a lucid and comprehensible manner. For practical interpretation and understanding, everyday activities are discussed in relation to each topic. Large number of numerical problems are also solved which make a student confident and encourage him to attempt unsolved numericals. This book, strictly adheres to the revised NCERT syllabus for Class IX, has been presented in two parts—First Term and Second Term on the guidelines of Continuous and Comprehensive Evaluation (CCE). Exercises have been bifurcated as per the requirement of Summative and Formative Assessments. All problems (Intext and Exercise questions) of revised NCERT textbook have been completely solved.
