## Overview

Physics Course 2 covers the second book of physics for class 11. The course starts with bulk properties of matter, giving scientific names to many phenomena that we observe around us. The course explains the peculiar behaviour of materials in different states of matter. This part is therefore very exciting. We will cover kinetic theory of gases and thermodynamics. Both these units will help us to justify the behaviour of gases for innumerable uses related to getting mechanical work done by heat. The challenging unit on oscillations and waves has been dealt with differently to explain kinematics and dynamic of oscillators. Wave motion as a method of energy propagation and properties of waves, the cases of superposition are explained with simplicity. The course has 4 units covered over 42 modules for better understanding. Based on feedback from teachers and students we have included modules after completion of each unit to enhance the unit by additional examples and explanations. This course has 4 units
• Properties of Bulk matter
• Thermodynamics
• Behaviour of perfect gases and kinetic theory of gases
• Oscillations and waves
The aim and design of the course is to develop a deeper understanding of different concepts in Physics. As you work through the course, you will find lecture videos, e-text, suggestions for problem solving methods, animations, practice questions, study guides. Assignments and Tests are provided to keep track of your achievements.This course is divided into 42 modules for better understanding.
