Vim lub zog gravitational yog inversely proportional rau lub square ntawm lub kev sib cais nrug ntawm ob qho khoom sib cuam tshuam, ntau dua kev sib cais nyob deb yuav ua rau muaj zog gravitational zog. Yog li thaum ob yam khoom sib cais los ntawm ib leeg, lub zog ntawm gravitational attraction ntawm lawv kuj txo.

Kuj paub, dab tsi yog lub zog gravitational ntawm ob yam khoom?

Cov gravitational quab yuam ntawm ob yam khoom yog proportional rau lawv pawg thiab inversely proportional mus rau square ntawm nyob deb nruab nrab lawv qhov chaw.

puas yog gravitational quab yuam ib txwm? Lub ntiaj teb ib txwm tsim cov ib yam acceleration ntawm txhua yam khoom. Txawm tias cov gravitational quab yuam Lub ntiaj teb exerts ntawm cov khoom yog txawv, lawv pawg tsuas yog sib txawv, yog li ntawd cov nyhuv peb soj ntsuam (acceleration) yog lub ib yam rau txhua tus. Lub ntiaj teb lub zog gravitational accelerates cov khoom thaum lawv poob.

Hais txog qhov no, ua li cas rau lub zog ntawm gravitational attraction ntawm ob yam khoom me me?

Lub zog ntawm lub gravitational quab yuam ntawm ob yam khoom nyob ntawm ob yam, huab hwm coj thiab nyob deb. tus zog ntawm lub ntiajteb txawj nqus cov masses exert rau ib leeg. Yog hais tias ib tug ntawm cov masses yog doubled, lub zog ntawm lub ntiajteb txawj nqus nruab nrab tus khoom yog ob npaug. nce, cov zog ntawm lub ntiajteb txawj nqus txo.

Peb txoj cai ntawm lub ntiajteb txawj nqus yog dab tsi?

Newton tus Peb Txoj Cai ntawm Motion thiab nws Law of Gravity tej zaum yog tus nto moo tshaj plaws ntawm tag nrho cov physics. Lawv tswj hwm qhov kev txav ntawm cov khoom uas peb pom hauv peb lub neej txhua hnub. Nyob rau hauv ob qho tib si cov lus tsa suab hloov. Newton thib ob Txoj cai of Motion hais tias quab yuam yog sib npaug rau qhov loj ntawm cov khoom lub sij hawm nws acceleration.
