Physics

Physics is a branch of science which deals with the nature's law. It explains early all "Why" of the life. Physics is the natural science that studies material, fundamentals of motion, space, time, energy, force etc. The scope of Physics extended from quantum level to the galactic magnitude. It is highly disciplined stream.  The main sub branches of physics are:

1. Measurements & Error

2. Motion & Classical Mechanics

3. Energy, Stress & Strength

4. Thermodynamics, Statistical & Gaseous Behavior

5. Gravity, Projectile & Planetary Motion

6. Fluid & Liquid

7. Optics and Photo-Electric Effect

8. Electricity & Magnetism

9. Electronics & Mechantronics

10. Atomic & Nuclear 

11. Quantum Physics

12. Logic Theory & Communication

13. Material Physics

14. Astrophysics

Advances in physics often enable advances in new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus. 

Physics is highly related to mathematics. Advancement in mathematics, specially in Calculus, allows exploration of new dimensions in physics and solving of complex problems.  Nearly all problems of physics can be solved by using Calculus.  Statistical mathematics has solved gaseous states at sub-temperature level.  Advancements are made in quantum physics and astro-physics but hundreds of complex problems are unsolved till date.  

Here, notes prepared for students are intended to Senior Secondary Levels. The concepts of physics are explained extensively to make it interesting.  Illustrations are used for each problem. Graphics are updated regularly.   Physics and mathematics are interlinked, therefore mathematical notes (see mathematics link) are written with collaborating physical problems.  Problems related to mathematics and physics are interlinked and mixed in both subjects.

All the best.
