Cisimleri D\u00fcnya\u2019n\u0131n merkezine do\u011fru \u00e7eken kuvvet. Yer \u00e7ekimi kuvveti, Ay\u2019\u0131 D\u00fcnya \u00e7evresinde y\u00f6r\u00fcngede tutar ve Ay\u2019\u0131n y\u00f6r\u00fcngeden kurtularak uzayda uzakla\u015fmas\u0131n\u0131 \u00f6nler. Bir cisme etki eden yer \u00e7ekimi kuvvetine o cismin a\u011f\u0131rl\u0131\u011f\u0131 denir.<\/p>\n
H\u0131z verilmeden y\u00fcksekten b\u0131rak\u0131lan cisimler, a\u011f\u0131rl\u0131klar\u0131 nedeniyle yere do\u011fru hareket ederler. Bu harekete serbest d\u00fc\u015fme denir. Cisimleri harekete ge\u00e7irebilmek i\u00e7in kuvvet uygulamak gerekir. Ancak serbest b\u0131rak\u0131lan bir cisme kuvvet uyguland\u0131\u011f\u0131 zaman bile cisim d\u00fc\u015fmeye devam eder. Bunun nedeni yer \u00e7ekimi kuvvetidir. Serbest d\u00fc\u015fen cisimler, Newton\u2019un \u0130kinci Hareket Yasas\u0131\u2019na g\u00f6re ivme kazan\u0131r. Buna yer \u00e7ekimi ivmesi denir. Serbest d\u00fc\u015fen cisimler yer \u00e7ekimi ivmesinin etkisiyle d\u00fczg\u00fcn h\u0131zlanarak yere d\u00fc\u015fer. Yer \u00e7ekimi kuvveti sabit oldu\u011fu i\u00e7in yer \u00e7ekimi ivmesi de sabittir; yani d\u00fc\u015fen bir cismin h\u0131z\u0131n\u0131n art\u0131\u015f h\u0131z\u0131, hep ayn\u0131 kal\u0131r ve cisim d\u00fc\u015ft\u00fc\u011f\u00fc s\u00fcrece her ge\u00e7en saniyede h\u0131z\u0131 ayn\u0131 miktarda artar.<\/p>\n
A\u011f\u0131rl\u0131k, Newton\u2019un genel \u00e7ekim yasas\u0131na g\u00f6re \u00e7ekim kuvvetleri sonucu olu\u015fan bir b\u00fcy\u00fckl\u00fckt\u00fcr. Yery\u00fcz\u00fcnde yerin merkezinden uzakla\u015ft\u0131k\u00e7a cisimlerin a\u011f\u0131rl\u0131\u011f\u0131 azal\u0131r. Bir cismin a\u011f\u0131rl\u0131\u011f\u0131 (G) o cismin k\u00fctlesi (m) ile bulundu\u011fu yerin \u00e7ekim ivmesi (g) \u00e7arp\u0131larak hesaplan\u0131r. Bir cismin a\u011f\u0131rl\u0131\u011f\u0131, bulundu\u011fu yere g\u00f6re de\u011fi\u015fir. Ay\u2019\u0131n k\u00fctlesi ve yar\u0131\u00e7ap\u0131 D\u00fcnya\u2019ya g\u00f6re daha k\u00fc\u00e7\u00fckt\u00fcr. Bu y\u00fczden bir cismin Ay\u2019daki a\u011f\u0131rl\u0131\u011f\u0131 D\u00fcnya\u2019daki a\u011f\u0131rl\u0131\u011f\u0131n\u0131n yakla\u015f\u0131k 1\/6\u2019s\u0131 kadard\u0131r. Bir cismin k\u00fctlesi de madde miktar\u0131n\u0131n bir \u00f6l\u00e7\u00fcs\u00fcd\u00fcr ve ay\u0131rt edici bir \u00f6zelliktir. Hi\u00e7 de\u011fi\u015fmez. D\u00fcnya\u2019dan Ay\u2019a do\u011fru gidildik\u00e7e D\u00fcnya\u2019n\u0131n \u00e7ekim kuvveti azal\u0131r ve Ay\u2019\u0131n \u00e7ekim kuvveti artar. Bu iki \u00e7ekim kuvvetinin e\u015fit oldu\u011fu yerde cismin k\u00fctlesi de\u011fi\u015fmedi\u011fi h\u00e2lde a\u011f\u0131rl\u0131\u011f\u0131 s\u0131f\u0131r olur.<\/p>\n
Yer \u00e7ekimi kuvvetinin, cismin k\u00fctlesine ve cismin yerin merkezine olan uzakl\u0131\u011f\u0131na ba\u011fl\u0131d\u0131r. Cismin k\u00fctlesi artt\u0131k\u00e7a cismin \u00fczerindeki yerin \u00e7ekim kuvveti de artar. K\u00fctleler aras\u0131ndaki \u00e7ekim kuvvetiyle ilgili olarak Newton, g\u00fcn\u00fcm\u00fczde de ge\u00e7erli olan Genel \u00c7ekim Yasas\u0131\u2019n\u0131 bulmu\u015ftur. Bu yasaya g\u00f6re, herhangi iki cisim birbirini, k\u00fctleleri \u00e7arp\u0131m\u0131yla do\u011fru orant\u0131l\u0131, k\u00fctle merkezlerini birle\u015ftiren uzakl\u0131\u011f\u0131n karesiyle ters orant\u0131l\u0131 bir kuvvetle \u00e7eker.<\/p>\n
