Theory of universal Gravitation

Theory of universal Gravitation

And the potential is determined by the surrounding mass distribution by Poisson s partial differential equation = 4. This formulation is entirely equivalent to Newton s law of gravitation. Because a test particle s acceleration depends only on the potential generated by matter in the surroundings, the…

Gravitational constant 9.81

Gravitational constant 9.81

Summary: The term g is based on the pull of gravity. NASA had a definition in their 1965 dictionary of Technical Terms for Aerospace Use: g or G An acceleration equal to the acceleration of gravity, 980.665 centimeter-second-squared, approximately 32.2 feet per second per second at sea level; used as…

Universal gravitational formula

Universal gravitational formula

States that the gravitational force between two objects is proportional to the product of their masses and inversely proportional to the square of separation between them. This equation is a result of Isaac Newton s Law of Universal Gravitation, which states that quantities of matter attract other matter…

Higgs boson LHC

Higgs boson LHC

Today during the 50th session of “Rencontres de Moriond” in La Thuile Italy, the ATLAS and CMS experiments presented for the first time a combination of their results on the mass of the Higgs boson. The combined mass of the Higgs boson is mH = 125.09 ± 0.24 (0.21 stat. ± 0.11 syst.) GeV, which corresponds…

Theories, and laws

The principles and theories of science have been established through repeated experimentation and observation and have been refereed through peer review before general acceptance by the scientific community. Acceptance does not imply rigidity or constraint, or denote . Instead, as new data become available…

Gravitational force for Kids

Gravitational force for Kids

Gravity Gravity represents the attraction between objects. All objects with mass are affected by gravity. Gravity acts like a magnet — pulling objects together. What causes gravity is not really known. The Earth has gravity. Gravity holds everything close to this planet. Trees, water, animals, buildings…
