This is the second book from the series Baby Steps In Physics, but can be read as a standalone. This book, as the previous one, teaches how to solve physics problems by baby steps. The book features problems and solutions worked out in detail. The problems are arranged by increasing level of difficulty that allows the student to use this book independently. Indeed, this book is only a second step towards understanding how to solve physics problems. However, the book encourages personal confidence in problem-solving and develops the student's knowledge of physics.
