What is the acceleration experienced by a 1200kg object as it falls?

If we may ignore air resistance ... and we always do for calculations that

involve falling objects ... an object with 1200kg of mass accelerates at the

rate of about 9.8 meters per second-squared, if it's on or near the surface

of the Earth.

That acceleration is the same as that of a falling elephant, bowling ball, car,

rock, leaf, or feather, in the absence of air resistance. In the absence of air

resistance, acceleration in free fall doesn't depend on the mass, weight, size,

shape, color, temperature, gender identification, or national origin of the falling

objects. Without air resistance, all objects fall at the same rate, and ANY two

objects that are dropped from the same height at the same time hit the ground

at the same time.
