Acceleration due to gravity is the acceleration of a freely falling body. Free falling means to drop vertically with no air resistance and an acceleration that doesn't change, or that is constant. The symbol for acceleration due to gravity is the letter g. The acceleration due to gravity, g is directed towards the center of whatever object gravity is draw towards, for example Earth, or any other planet.

An equation can be used to find the gravitational acceleration in different places. This equation is …

is a constant, called the universal gravitational constant, which is equal to 6.67 × 10-11 N·m2/kg2. is the mass of the object in which gravitational acceleration is being found. is the radius of the object. There is a negative sign in front of the equation because objects in free fall always fall downwards toward the center of the object.

The acceleration due to gravity is 1.62 m/s2. This is approximately 1/6 that of the acceleration due to gravity on Earth, 9.81 m/s2.

What is the universal gravitational constant, the mass of the earth, and the radius of the earth?

The universal gravitational constant, denoted "G," is equal to 6.672e-11. The mass is 5.9736 e24 kg, and the radius is 6378.1 km at the equator and 6356.8 km at the poles.
