- Law of physics is same everywhere in the universe.
- for example law of gravitation is same everywhere in the universe.
- at moon surface the acceleration due to gravity is 1/6th time lesser than the earth but in both the places acceleration due to gravity is present and laws of gravitation is also present.
- The law of gravitation on moon is as same as law of gravitation on earth.
- there are some conservation law which helps in understanding some physical phenomenon.
- Law of conservation of energy:- The energy of whole system is conserved.
- Law of conservation momentum:- The momentum of whole system is conserved.
- Law of conservation mass:- The mass of whole system is conserved.
After the theory of relativity given by Einestein ( mass can be converted into energy and energy can be converted into mass) The conservative theory of mass and energy are changed and now it is like mass +energy of a whole system is conserved.
