Neglecting air resistance ... all of them.
In a vacuum, solid and hollow objects fall at the same speed due to gravity. However, in the presence of air resistance, hollow objects might fall more slowly compared to solid objects of the same mass and shape, as air resistance affects hollow objects differently.
They don't. All objects fall at the same rate of speed because of weight.
In a vacuum, air resistance is eliminated, and all objects fall due to gravity alone. The acceleration due to gravity is the same for all objects regardless of their mass, so they fall at the same speed in a vacuum.
In the absence of air, all objects fall with the same acceleration. That means that at the same time after the drop, all objects are moving at the same speed.
Galileo
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
no depening on how heavy it is that's the speed it will go. information by wwtpody:)
The only reason falling objects don't fall at the same speed on Earth is the countering force of wind resistance. Without air, all objects would fall at the same rate, regardless of mass (ex. Galileo's ball experiments, as well as the hammer and feather experiment on the Moon).
They fall at the same speed, if there is no outside force acting on it (ie. air resistance, wind etc.)
In a vacuum, all objects fall at the same speed regardless of shape or weight due to gravity exerting the same force on them. However, in the presence of air resistance, objects with different shapes will fall at different speeds due to variations in air resistance.
Galileo Galilei did.
Galileo Galilei, an Italian scientist and astronomer, is credited with challenging the teachings of the church by proposing that objects fall at the same rate of speed regardless of their mass. This idea contradicted the Aristotelian view supported by the church at the time.
