Pernyataan manakah adalah benar untuk menerangkan tentang Hukum Kegravitian Semesta Newton? Which statement is true to explain Newton’s Universal Law of Gravitation?
Daya graviti merupakan satu pemalar kegravitian. Gravitational force is a gravitational constant.
Daya graviti bertambah secara linear dengan hasil darab jisim dua jasad. The force of gravity is increase linearly to the product of the mass of two bodies.
Daya graviti boleh menjadi daya tarikan atau daya tolakan. Gravitational force can be an attractive force or a repulsive force.
Daya graviti berkadar songsang dengan kuasa dua jarak di antara pusat dua jasad.
The force of gravity is inversely proportional to the square of the distance between the centers of the two bodies.
Hukum kegravitian semesta Newton di berikan oleh rumus:
Newton’s Universal Law of Gravitation is given by the equation:
G adalah merupakan
G known as
Pecutan graviti / Gravitational acceleration
Pemalar graviti / Gravitational constant
Daya graviti / Gravitational force
Medan graviti / Gravitational field
Hukum kegravitian Newton boleh digunakan untuk jasad-jasad
The Newton law of gravitation is applicable only to bodies
di bumi / on Earth
di planet / on planets
