Galileo showed that all bodies fall at the same speed under gravity. He performed his experiments assuming air resistance is ignored.

Galileo Galilei is reported (see addendum) to have dropped a ten-pound weight and a one-pound weight off the Leaning Tower of Pisa, and proved that both fall at the same speed. Of course, a more general principle was being demonstrated, the fact that objects of any weight fall at the same speed (with the same acceleration, actually). Does this experiment fit the bill? Does it, in fact, prove that objects of any weight fall with the same speed or acceleration?
both will fall at the same time
all things fall at the same speed
iT DEPENDS IF THE BALL IS LIGHT THE LIGTER MOSTLIKLEY TO HAVE THE SAME SPEED.
Quarters and feathers would only fall at the same speed in a vacuum. In air, the quarter would fall faster, as it has less air resistance.
A marble and a bowling ball fall at the same acceleration speed. Anything with the exact same shape falls at the same velocity. 10 meters/s/s
In the absence of air, everything falls with the same acceleration, and reaches the same speed in the same amount of time after being dropped. If things fall through air, though, this isn't true.
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
In a vacuum.
