How do you calculate the gravitational acceleration of an object?

To calculate the gravitational acceleration of an object, you can use the formula: acceleration due to gravity (g) gravitational force (F) / mass (m). The gravitational force can be calculated using Newton's law of universal gravitation, which is F G (m1 m2) / r2, where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between their centers.
