Explain the Universal law of gravity and its calculated form as well as the value of G.
Answers
Answer:
Stated in modern language, Newton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Newton's universal law of gravitation: Every particle in the universe attracts every other particle with a force along a line joining them. ... In equation form, this is F=GmMr2 F = G mM r 2 , where F is the magnitude of the gravitational force.

G is called the constant of gravitation and is equal to 6.67 × 10−11 newton-metre2-kilogram−2.
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= g*m1*m2/r2
Where, G is the universal gravitation constant and its value is 6.67×10-11 Nm2kg-2
