#### More to Know

1. The word PHYSICS comes from a Greek word meaning NATURE.
2. The word भौतिक विज्ञान related to the science is derived from Sanskrit word भौतिकी.
3. Physics deals with the study of basic laws of nature related to matter, energy and their manifestation in different phenomena.
4. The basic laws of physics are universal and are applied widely in different conditions and contexts.
5. The physical quantities that remains unchanged with time is called conserved quantity.
6. The gravitational force, electromagnetic force, strong nuclear force and weak nuclear force are the four fundamental forces in nature.
##### Fundamental laws of Physics
• Law of conservation of Energy: The amount of total energy in the universe remains constant. Energy can neither be created nor be destroyed, it can just be converted from one form to the another.
• Law of conservation of Charge: During any process taking place in an electrically isolated system, the algebraic sum of the charges always remains constant.
• Law of conservation of Linear Momentum: If the resultant external force on a system is zero, the total linear momentum of the system remains constant.
• Law of conservation of Angular Momentum: If the resultant external torque acting on a system is zero, the total angular momentum of the system remains constant.
