Sindh Class 9 Physics Notes
Q.1 what is physics? Also, describe its important branches?
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.
