Wannan kwarewa ya ba da dalilin ba kawai ga halittar manufar gravitational hanzari (USP), amma kuma ya bayar da shawarar cewa free fall (watau fadowa jiki, wanda ba a shafi wani sabani da karfi) ne kawai zai yiwu a wani wuri. A cikin iska, duk da haka, wanda shine tushen juriya, duk jikin ta motsa tare da hanzari.

Kan bango na data nuna cewa cikin hanzari saboda nauyi a kan sauran taurari ne daban-daban daga gare su a duniya. Masana kimiyya zo ga ƙarshe cewa shi za a iya bayyana ta da wadannan dabara:

g = G x M duniyar tamu / (R duniya) (2)

A sauki sharuddan: G (da gravitational m (6,67 • 10 (-11) m2 / s2 ∙ kg)) ne ta tara da M - taro duniyar tamu-raba da R - duniya radius Squared. Alal misali, za mu iya samun cikin hanzari da nauyi a kan Moon. Sanin cewa ta taro ne daidai 7.3477 * 10 (22) kg da wanda radius - 1737,10 km, mun sami cewa USP = 1.62 N / kg. Kamar yadda aka nuna, hanzari a biyu taurari ne sosai daban-daban daga juna. A musamman, a cikin duniya shi ne kusan 6 sau more!
