Class 9th Physics Chapter 9
Nature of Science
Here we discuss about that Physics is the fundamental of science that
deal with the constituents in the universe, matter energy space time and
their mutual relationships.
Braches of Physics
1. Mechanics
It is studying the motion which is effect of
influence motion. Its is based on newton’s law
of motion and gravitation know as classical
mechanics.
2. Heat and thermodynamics
Its deal with the thermal energy possessed by
the material and flow used one body to
another.
3. Acoustics
Its deals with the nature and physical aspect of audible sound energy.
4. Optics
Its deal with the physical aspect of visible light.
5. Electromagnetism
It is studying the electromagnetic phenomenon.
