1.G stands for Newton's universal gravitational constant, whereas g stands for the acceleration due to gravity at a certain point.
2.G = 6.67300 × 10-11 N.m2.kg-2. G is a constant throughout space and time. g = 9.8 m.s-2. g is a variable quantity.
3.G is a scalar quantity whereas g is a vector quantity.
4.G is a constant at a given location, where g depends upon M and r.
According to Newton's law of universal gravitation the force of attraction between two bodies is given by
F = GMm/r2, where the symbols stand for their usual well known meanings. Also the weight of a body of mass m is F = mg. So mg = GMm/r2, or g = GM/r2
