Question

Calculate the accleration of the moon towards the earth center ?

Answer 1

 A=-(G*m)/r^2. Where a = acceleration from gravity. G = A constant number* m = mass of the object (earth or moon)

Answer 2

Explanation:

Acceleration Due to Gravity Formula

Near the Earth's surface, the acceleration due to gravity is approximately constant. However, at large distances from the Earth, or around other planets or moons, the acceleration is different. The acceleration due to gravity depends on the mass of the body, the distance from the center of mass, and a constant G, which is called the "universal gravitational constant". Its value is = 6.673 x 10-11 N·m2/kg2.

g = acceleration due to gravity (units m/s2)

G = the universal gravitational constant, G = 6.673 x 10-11N·m2kg2

m = mass of a large body (for example, Earth)

r = the distance from the center of mass of the large body.
