$\underline\pink{ɢʀᴀᴠɪᴛʏ :}$

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

In SI units, G has the value 6.67 × 10-11 Newtons kg-2 m2. The direction of the force is in a straight line between the two bodies and is attractive. Thus, an apple falls from a tree because it feels the gravitational force of the Earth and is therefore subject to “gravity”

$\bold\red{\fbox{\sf{Law\:of\: gravity}}}$

Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

$\bold\red{\fbox{\sf{Formula}}}$

• $\sf \orange{F=G{\frac{m_1m_2}{r^2}}}$

• $\sf \blue{F = force}$

• $\sf \orange{G = gravitational \: constant}$

• $\sf \blue{m_1 = mass \: of \: object \: 1}$

• $\sf \orange{m_2 = mass \: of \: object \: 2}$

• $\sf \blue{r = distance \: between \: centers \: of \: the \: masses}$

Answer 2

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe.

$\sf{\underline{\overline{\pink{Formula}}}}$

$\sf \red{F=G{\frac{m_1m_2}{r^2}}}$

$\sf \blue{F = force}$

$\sf \red{G = gravitational \: constant}$

$\sf \blue{m_1 = mass \: of \: object \: 1}$

$\sf \red{m_2 = mass \: of \: object \: 2}$

$\sf \blue{r = distance \: between \: centers \: of \: the \: masses}$
