För andra betydelser, se Gravitation (olika betydelser). Gravitationen håller solsystemets planeter i omloppsbana kring solen. Notera: Bilden är ej skalenlig. Gravitation (av latin gravis = tung), i vardagligt tal ofta likställd med tyngdkraft, är en av universums fyra fundamentala krafter. The gravitational field is a vector field that describes the gravitational force that would be applied on an object in any given point in space, per unit mass.

Finns det någon punkt i rymden där gravitationen är +/- noll? Dvs. om man åker från jorden mot månen kommer man till en punkt där jordens och månens gravitation är lika. Isaac Newton. Einsteins formulering [ redigera redigera wikitext ]. Experiment barn utomhus
Formeln för gravitationslagen är F = GMm/r2. F är själva gravitationskraften, som mäts i newton. G är den universella gravitationskonstanten och alltså ett fast värde. M och m är uttryck för två olika kroppars massor. Det kan exempelvis vara solens och jordens massor eller jordens massa och en människas kroppsvikt. Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction , 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.

The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation). [2] [3] It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is given by the norm. Einstein began to toy with this idea in the form of the equivalence principle , a discovery which he later described as "the happiest thought of my life. Riess Facts".

Newton’s law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. Isaac Newton put forward the law in From Atoms to Galaxies: A conceptual physics approach to scientific awareness. Assuming a spherically symmetrical planet, the strength of this field at any given point above the surface is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.

In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction which causes mutual attraction between all things that have mass. Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 Bibcode : Schpj Oxford University Press.

By rearranging Equation and substituting r = R E, the apparent weight at the equator is. Fs = m(g − REω2). The angular speed of Earth everywhere is. ω = 2π rad 24 hr × s / hr = × 10 − 5 rad / s. Substituting for the values of R E and ω, we have R Eω2 = m/s 2. Carlip, Class. Retrieved 26 May
