Question

In the equation for the gravitational force between two objects, what does G represent?

Answer 1

The G is represented as “Universal Gravitational constant” in the gravitational force equation acting between the two objects.

Explanation:

The force of gravitation is given by following equation, $\bold{F= \frac{- G (M m)}{r^2}}$

F - Force of gravitation,

G - Universal gravitational constant,

M - Mass of $1^{st}$ object,

m - Mass of $2^{nd}$ object,

R - Distance between two objects.

The negative sign here denotes that gravitational force is experienced along the line of separation of the two objects. And it also indicates that it is an attractive force between the two.

Answer 2

G is actually the universal gravitational constant.
6.674×10−11 m3⋅kg−1⋅s−2
This proportional to the product of the two objects masses and the inverse square of their distance.


This different from g which the local gravitational constant.
