An object was dropped from the plane with 1000 km above the ground with a mass of 300 kg. Find the acceleration of the object each second until it reaches the ground.

Explanation:

The acceleration due to gravity on earth is regardless of the mass of the object. This means, in the absence of air resistance, both a 3000 kg object and a 300 kg will accelerate at the same rate of towards  earth.

The reason the acceleration due to gravity is the same for all masses is that by grace of nature, the inertial mass of the object from  equals the gravitational mass from , resulting

which is the acceleration that only depends on the mass of earth and its radius, and not on the mass of the object.
