Class 11 Physics Chapter 1 – Important Concepts

Physics is a fundamental science that is concerned with understanding the natural phenomena that occur in the universe.

The various branches of Physics include – Mechanics, Thermodynamics, Electromagnetism, and Modem Physics.

The scope of Physics covers a magnitude of physical quantities such as mass, length, time, energy, and so on.

Physics deals with the macroscopic world such as the universe and galaxies as well as the microscopic world such as the nucleus of an atom.

Gravitational force is the force of attraction between any 2 bodies that is directly proportional to the product of their masses. It is inversely proportional to the square of the distance between them.

\(\begin{array}{l}F\propto \frac{(m_{1}m_{2})}{r^{2}}\end{array}\)

Electromagnetic Force is a physical interaction occurring between electrically charged particles.

Electromagnetic Force can be either attractive or repulsive.

Nuclear force is a force that acts between the neutrons and protons of atoms.

The nuclear force is the force that binds the nucleus together.
