The subject of physics is the subject of Newton

It is acceleration, velocity and momentum

We have to study refraction of light

Diffraction from fringes, dark and bright

Newton observed apple falling down a tree

And conclusion came with presence of gravity

Telescope and microscope helps to see objects

Which are'nt seen easily and direct

According to Newton's third law of motion

Every action has a reaction

Einstein proved light's dual nature

It travels as wave as well as particle

How sound produces, how motion occurs

Physics tells us blessings and curse.
