G stands for gravitational constant and his acceleration due to gravity

Relationships between G and g
G and g are both related to the force of gravity, but they represent different aspects of it.

G (Capital G)
- G is the universal gravitational constant, which is a constant value used in the equation for the force of gravity between two objects.
- It is a fundamental constant in physics and has a value of approximately 6.674 × 10^-11 N m^2/kg^2.
- G is used in the formula F = G * (m1 * m2) / r^2, where F is the gravitational force, m1 and m2 are the masses of the two objects, and r is the distance between them.

g (Small g)
- g represents the acceleration due to gravity, which is the acceleration experienced by an object due to the gravitational force of a massive body.
- On the surface of the Earth, the value of g is approximately 9.81 m/s^2.
- The acceleration due to gravity is the same for all objects at a given location, regardless of their mass.

Relationship between G and g
- The gravitational force between two objects depends on their masses and the distance between them, as given by the formula F = G * (m1 * m2) / r^2.
- The acceleration due to gravity experienced by an object is a result of the gravitational force acting on it, as given by the formula F = m * g, where m is the mass of the object.
- Therefore, while G is a constant used to calculate the gravitational force between two objects, g is the acceleration experienced by objects due to the gravitational force.
