<\/span> Berapakah konstanta gravitasi universal?<\/span><\/h2>\n

Konstanta gravitasi universal<\/strong> (G) adalah konstanta fisika yang digunakan untuk menghitung gaya tarik-menarik gravitasi antara dua benda. Nilai konstanta gravitasi universal adalah G=6.674\u00b710 -11<\/sup> N\u00b7m 2<\/sup> \/kg 2<\/sup> .<\/p>\n

Simbol konstanta gravitasi universal adalah huruf kapital G.<\/p>\n

Dalam Satuan Sistem Internasional (SI), satuan konstanta gravitasi universal adalah N m 2<\/sup> \/kg 2<\/sup> . Meskipun dalam Sistem Satuan C\u00e9g\u00e9simal, konstanta gravitasi universal dinyatakan dalam dyne\u00b7cm 2<\/sup> \/g 2<\/sup> . <\/p>\n

<\/span> Berapa nilai konstanta gravitasi universal?<\/span><\/h2>\n

Nilai konstanta gravitasi universal sama dengan G=6.674\u00b710 -11<\/sup> N\u00b7m 2<\/sup> \/kg 2<\/sup> .<\/strong> Namun, nilai ini hanyalah perkiraan, karena jumlah pasti konstanta fisika ini tidak diketahui.<\/p>\n

Faktanya, konstanta gravitasi universal adalah salah satu konstanta fisika yang paling sedikit diketahui secara pasti. Nilai konstanta gravitasi universal dianggap diketahui dengan kesalahan 1 dalam 10.000.<\/p>\n

Sejauh ini, hanya lima tempat desimal dari konstanta gravitasi universal yang telah ditentukan dengan pasti, sehingga nilai paling tepat yang diketahui adalah G=6.67430\u00b10.00015.10 -11<\/sup> N m 2<\/sup> \/kg 2<\/sup> .<\/p>\n

Demikian pula, fakta bahwa nilai konstanta gravitasi universal yang belum ditemukan secara pasti membuat sulit untuk menghitung massa bintang karena nilainya juga tidak tepat, seperti massa Bumi atau Matahari. <\/p>\n

<\/span>Untuk apa konstanta gravitasi universal digunakan?<\/span><\/h2>\n

Terutama, konstanta gravitasi universal digunakan untuk menghitung gaya gravitasi antara dua benda.<\/strong> Dengan kata lain, konstanta gravitasi universal memungkinkan kita menemukan gaya tarik menarik dua benda.<\/p>\n

Demikian pula, konstanta gravitasi universal juga digunakan untuk menghitung massa benda langit, seperti Bumi, Bulan, atau Matahari. <\/p>\n

<\/span> Siapa yang menemukan konstanta gravitasi universal?<\/span><\/h2>\n

Keberadaan konstanta gravitasi universal tersirat dalam penerbitan hukum gravitasi universal Newton pada akhir abad ke-17. Oleh karena itu, fisikawan Isaac Newton-lah yang menemukan konstanta gravitasi universal, meskipun ia tidak menghitung nilainya.<\/p>\n

Kemudian pada tahun 1798, Henry Cavendish untuk pertama kalinya berhasil memperoleh nilai konstanta gravitasi universal, perkiraan yang diperolehnya adalah G=6.6\u00b10.041.10 -11<\/sup> N\u00b7m 2<\/sup> \/kg 2<\/sup> . Cavendish sampai pada nilai ini secara eksperimental.<\/p>\n

Sepanjang sejarah, semakin banyak penemuan yang dibuat tentang konstanta gravitasi universal, menjadikan nilainya semakin konkret. Hingga tahun 2018, ketika kelompok penelitian Tiongkok menemukan nilai konstanta gravitasi universal yang paling akurat hingga saat ini, yaitu G=6.67430\u00b10.00015\u00b710 -11<\/sup> N\u00b7m 2<\/sup> \/kg 2<\/sup> .<\/p>\n","protected":false},"excerpt":{"rendered":"
