What is G in physics?

Answer 1

G is typically Gibb's free energy or the "Gibb's Number" or "Gibb's Function"

If you also see H (enthalpy), T (absolute temperature in Kelvin) and S (entropy) then this is probably the case

However if you are dealing with streamline flow it may also be the Graetz number

Answer 2

In physics, G typically refers to the gravitational constant, denoted as ( G ). It is a fundamental physical constant that appears in the law of universal gravitation and is approximately equal to ( 6.67430 \times 10^{-11} , \text{m}^3\text{kg}^{-1}\text{s}^{-2} ).

Answer 3

G, the accepted symbol for the gravitational constant, is 6.67300 × 10-11 N(m/kg)^2 G is a natural unit (a famous example of which is the speed of light)

Answer 4

In this equation G is a constant called gravitation constant
