What is the acceleration produced in a freely falling body of mass 10kg? (Neglect air resistance)

The acceleration depends on what planet you select for the experiment. On Earth, it's about 9.8 m/s^2. We've known for about 500 years that the mass of the falling object makes no difference. If there were no air, a feather and a schoolbus would fall with the same acceleration.

What about gravity? Is this on earth? Earths gravity is approximately 9.8m/s^2
