## Sindh Class 9 Physics Notes

PHYSICS :> The branch of science which deals with the study of properties, energy, and their mutual relationship is called physics”

Some important branches of physics are given below:

- Mechanics:-It deals with the motion of bodies under the action of force.

- Heat and thermodynamics:-It deals with the study of nature, properties. and uses of heat energy. And also deals with transformation of heat energy from one for to another form.

- Optics:- it deals with the prorogation, reflection, refraction, dispersion and wave properties of light.

- Electricity and magnetism:- it deals with the study of charges at rest as well as in motion.

- Atomic physics:-it deals with the structure and properties of individual atom.

- Nucleus physics:- it deals with the structure and properties of nuclease of an atom.

- Solid state physics:-it deals with the properties of matter in solid state.

- Particle physics:- it deals with the study of elementary particles.

- Plasma physics:-which is the fourth state of matter. And occurs in ionized state.

- Quantum physics:-quanta is studied is this branch which is the discrete and individuals particle of energy.

- Semiconductor physics:- whose properties lie b/w conductor and insulator.

- Astro physics:- it deals with the study of heavenly bodies.

- Bio physics:- study of biology based on the principle of physics is called bio physics.

- Geo physics:- it deals with the study of earth and atmospheric.

- Health physics:- it deals with the study of diseases and their treatment.
