Makes sense, why test it?
Excuse me, I have to get back to wiping my ass with the communal sponge-on-a-stick.

This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Don't forget your lead cookware and lead infused wine!
Makes everything sweeter. And the mental instability is less of a hindrance in times when people were regularly crucified.
Lucretius, writing in 50 BCE:
Whatever falls through water or thin air, the rate Of speed at which it falls must be related to its weight, Because the substance of water and the nature of thin air Do not resist all objects equally, but give way faster To heavier objects, overcome, while on the other hand Empty void cannot at any part or time withstand Any object, but it must continually heed Its nature and give way, so all things fall at equal speed, Even though of differing weights, through the still void.
- De Rerum Natura book 2 lines 230-239
I was literally just writing about him nailing survival of the fittest too.
He's still arguing that heavy objects would fall faster when dropped anywhere on Earth, though, specifically bringing up air resistance as the reason. His argument is that they would fall at the same rate in a vacuum.
But that's true, isn't it? Putting aside volume and shape.
He's close, but not quite there. Air resistance slows things, and in a vacuum all things will fall at the same rate, yes. But, weight has zero impact on the rate an object falls through the atmosphere. Air resistance affects things based on their shape and permeability. He's still saying that a heavier object will fall faster in atmosphere, all other things being equal, which is false.
He clearly knows air resistance is a thing, he just doesn't understand how it works.
Hi. Physicist here. You are absolutely wrong. The mass of an object does not affect the magnitude of force of air resistance which acts upon a falling object. But the acceleration that object will have is given by Newton's second law as Force divided by mass. So a heavy and a light ball with the same shape will experience the same air resistance, but the heavy ball will "care less" and thus fall faster.
