Question

What do we mean when we say that G is the universal grav
itation constant?​

Answer 1

Answer:

According to Newton's law of universal gravitation, the attractive force (F) between two point-like bodies is directly proportional to the product of their masses (m1 and m2) and inversely proportional to the square of the distance, r, between them: The constant of proportionality, G, is the gravitational constant.

Answer 2

Answer:

G is called Universal Gravitation Constant because its value i.e. 6.67 x 10-11 Nm2kg-2 is constant thought the universe.
