  A similar size chunk of iron and coal would have done the experiment just fine. Any two objects of the same shape and size but significantly different densities.

    If two objects have the same size and shape, the force applied by air resistance will be the same. However, if two objects have different mass, that same force will result in different acceleration.

      While that is true, two properly selected objects (such as the ones mentioned above) can reduce the effect of air resistance to levels negligible to human perception, demonstrating that heavier objects do not intrinsically fall faster.

        Not at all. Our air is made up of physical objects (molecules of oxygen and nitrogen, mostly). Things with more mass, more quickly knock those out of the way.

        For a demonstration you can see and more easily wrap your head around, take something just barely heavier than water, and a similarly sized heavy rock and drop them in a pool. You’ll see how much quicker the rock gets to the bottom, because it displaces the water so much faster. Our atmosphere is the exact same.

      So change the shape, a long copper rod and clump of coal.

        If you do that then they definitely won't fall the same.

    And the iron would hit the ground much faster because it pushes air molecules out of the way quicker.

  Nope, denser objects fall faster than less dense ones (through the air). Remember: A kilogram of feathers is just as heavy as a kilogram of lead.

    I’ll still choose to be hit by the feathers.

      You’ll get hit by what you’re told to get hit by and you’ll like it.

    Not really true, it’s definitely possible for a less dense object to fall faster than a denser one. A drop of water will fall faster than a parachute made of aluminum.

    Technically it’s objects with a higher mass-to-drag ratio, but most of the time it’s close enough
