The acceleration due to gravity is created by the gravitational force between two objects. According to Newton's law of universal gravitation, any two objects with mass will attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
The formula for the gravitational force between two objects is:
F = (G * m1 * m2) / r^2
Where: F is the gravitational force G is the gravitational constant (approximately 6.67430 x 10^-11 N(m/kg)^2) m1 and m2 are the masses of the two objects r is the distance between their centers
When an object near the surface of the Earth is experiencing the acceleration due to gravity, it is being attracted toward the center of the Earth by the gravitational force between the object and the Earth. The magnitude of this force depends on the mass of the object and the mass of the Earth, as well as the distance between their centers.
The acceleration due to gravity, denoted as "g," is defined as the gravitational force per unit mass. It represents the rate at which an object would accelerate if no other forces were acting upon it. Near the surface of the Earth, the average value of acceleration due to gravity is approximately 9.8 meters per second squared (m/s^2).
In summary, the acceleration due to gravity is created by the gravitational force between two objects, such as an object and the Earth. The mass of the object and the distance between their centers determine the strength of the gravitational force and consequently the acceleration experienced by the object.
