Question

Explain the universal law of gravity and its calculated form as well as the value of G.​

Answer 1

Answer:

The universal law of gravity states that every object with a force called gravitational force. The force acting between two objects is directly proportional to the product of masses and inversely proportional to the square of the distance between their centers.

For two objects of masses m1 and m2 and the distance between them are r, the force (F) of attraction acting between is given by universal law of gravitational as:

F=

$\frac{g \times m1 \times m2}{ {r}^{2} }$

Where, G is the universal gravitation constant and its value is 6.67×10-11 Nm2kg-2.

Answer 2

The universal law of gravitation states that any particle in the universe attracts the other particles with a force that that is directly proportional to the product of their masses and inversely proportional to the square of distance between them. The universal law of gravitation was given by Newton.

• The equation for the universal law of gravity is as follows:

F ∝ m₁m₂/ r²

F = Gm₁m₂ /r²

Where m₁ and m₂ are the masses of the two objects,

F is the gravitational force between them,

r is the distance between their centres

G is the universal Gravitational constant.

• The value of G = 6.673×10⁻¹¹ Nm²/kg².
