Classical physics is part of physics which deals with studying things like movement, light, gravity, and electricity.

the motion of a ball and the motion of dust particles is described by Classical physics.

Some other things such as Newton’s law of motion, Newton’s law of gravitation, Laws of thermodynamics, Maxwell’s electromagnetism and Lorentz force are also described by Classical physics.

It also describes the system of heavenly bodies like the Sun, the Earth and the Moon and its planetary motions. However, it is fail to describe small sized particle of less than range of 10^-6 m.
