What is Simple Harmonic motion? Simple Harmonic Motion is the simplest form of oscillatory motion. Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position. The direction of this restoring force is always towards the mean position. Notes of chapter are given below after some important graph please download in pdf .

Kinetic theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules. Further, the theory explains that gas pressure arises due to particles colliding with each other and the walls of the container. Kinetic theory of gases also defines properties such as temperature, volume, pressure s well as transport properties such as viscosity and thermal conductivity as well as mass diffusivity. It basically explains all the properties that are related to the microscopic phenomenon. The significance of the theory is that it helps in developing a correlation between the macroscopic properties and the microscopic phenomenon. In simple terms, the kinetic theory of gases also helps us study the action of the molecules. Generally, the molecules of gases are always in motion and they tend to collide with each other and the walls of the containers. In addition, the model also helps in
