Physics in class IX opens the doors to understanding fascinating concepts such as motion, gravitation, sound, force, work, power, energy and more which are the very basic and crucial concepts of our daily life.
Most topics learnt in Class 9 are also to be learnt for the entrance exams in a detailed and thorough manner, requiring an in-depth knowledge of the concepts. Students need to build up their concepts from class IX only.In Class IX, the student is introduced to the fundamental Newton’s laws of motion and the three equations of motion. This forms the basis of entrance-level kinematics. It requires a clear understanding of motion and related concepts. Similarly a class IX student is introduced with gravitation and its different laws which make him/her to realise the importance of the force which tends to bind us all to earth. In chapter sound, you will get a crisp and brief explanation of important topics like production and propagation of sound, medium, waves, characteristics of sound, range of sound, reflection of sound and its applications. In chapter work, power and energy, student will thoroughly understand the meaning of work, energy, types of energy that we require on a daily basis. In this manner, concepts of physics in class IX are foundation stone of detailed physics which a science student must know.
