Foundation Science Physics For Class 9th and 10th , academic book goal is to provide students with a strong foundation in science. Common, everyday experiences are widely used to illustrate scientific principles. This should make the reading interesting as well as help students realize the intimate relationship between science and nature. When a new equation is derived or a new concept is introduced, generally, a numerical example follows. These in-text numerical examples should help in clarifying the exact meaning of the terms in the equation and in the elaboration of the concept. The main points discussed in a chapter are collected at one place under the heading Points to Remember. In each chapter a separate section on solved problems illustrates how the equations and laws discussed in that chapter can be used in working out problems. There are exercise sets to stimulate the minds of the students. The exercises are not only to test the understanding of the students, but also to make it better. Carefully formulated exercise problems encourage the students to think deeply about the principles involved and in the process make the student's understanding of the concept clear. A special section called Postscript is given at the end of some chapters that discusses some interesting facts related to the subject of that chapter. In some cases simple activities or projects are suggested. These activities can be performed without any special equipment.
