Linear Momentum and Collisions - Sanjay Kumar - Bog

This physics book is the product of more than fifteen years of teaching and innovation experience in physics for JEE main and Advanced aspirants. Our main goals in writing this book are-- to present the basic concepts and principles of physics that students need to know for JEE-advanced and other related competitive exams.- to provide a balance of quantitative reasoning and conceptual understanding, with special attention to concepts that have been causing difficulties to student in understanding the concepts.- to develop students' problem-solving skills and confidence in a systematic manner.- to motivate students by integrating real-world examples that build upon their everyday experiences.What's New?Lots! Much is new and unseen before. Here are the big four:1. Every concept is given in student friendly language with various solved problems. The solution is provided with problem solving approach and discussion.2. Checkpoint questions have been added to applicable sections of the text to allow students to pause and test their understanding of the concept explored within the current section. The answers to the Checkpoints are given in answer keys, at the end of the chapter, so that students can confirm their knowledge without jumping too quickly to the provided answer.3. Special attention is given to variable mass, impulse, and chain related problems, so that student can easily solve them with fun.4. To test the understanding level of students, multiple choice questions, conceptual questions, practice problems with previous years JEE Main and Advanced problems are provided at the end of the whole discussion. Number of dots indicates level of problem difficulty. Straightforward problems (basic level) are indicated by single dot (●), intermediate problems (JEE mains level) are indicated by double dots (●●), whereas challenging problems (advanced level) are indicated by thee dots (●●●). Answer keys with hints and solutions are provided at the end of the chapter.
