Where would a bowling ball and a napkin fall with the same acceleration?

Answer: In absence of any drag force - in space/in vacuum

Explanation:

A Bowling ball and a napkin would fall with the same acceleration in space where there is vacuum. Basically where there is no drag force and the two objects are freely falling under gravity. The two objects would fall with same acceleration due to gravity. The drag force depends on mass of the object and surface area and it acts in the opposite direction of motion thus changing the net acceleration of the body.

That would happen at any place where they don't have to

fall through air or anything else.

Examples:

- - on the moon

- - on an asteroid

- - on a comet

- - on Mercury

- - on Earth, in a vacuum chamber with all the air pumped out of it
