Something something friction
yeah everything is probably made of like, idk, earth water, fire and air or something idrk

When accounting for air resistance, heavy objects do fall faster than light ones. They couldn't test in a vacuum back then, they only knew how things work here in Earth's atmosphere.

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.
missingno@fedia.io 7 hours ago
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.
ColeSloth@discuss.tchncs.de 4 hours ago
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.

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

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

The thing that always gets me about the renaissance is Galileo:
He did those experiments with things falling down? Measuring speed?
Yeah. Without a clock.
The theory for how to build those came later, based on what Galileo did.

Man, being a cop must have sucked before they invented time.
Officer: do you know how fast you were going?
Lord: No, do you?
Officers: grumbles you’re free to go.
Carriage pulls away
Officer ClocknTime: For now, for now.

Doing the math: 1,000,000,000 x 0.5 = 500,000,000 grams of water droplets in our cloud. That is about 500,000 kilograms or 1.1 million pounds (about 551 tons). But, that “heavy” cloud is floating over your head because the air below it is even heavier— the lesser density of the cloud allows it to float on the dryer and more-dense air.

Try dropping your phone from a hot air balloon and see which one hits the ground first.

With same gravity constance everything fall down at the same speed, but only in a vacuum. In an atmosphere there count the air resistance of an object, even if they are made of the same material and weight, an iron sphere of 1 kg fall faster than a iron sheet of 1 kg.

That’s why Gallileo’s balls were so special.

With two metal balls, one solid and one hollow, you could rule out the role of resistance?
falcunculus@jlai.lu 1 hour ago
That’s clever, it would eliminate aerodynamism as a factor.
However results would still vary, because hollowing out the metal ball increases its buoyancy (see Archimedes’ principle).

They did figure out the earth was round and measure its size with sticks and shadows though, so that’s pretty cool.

Did you know that two identical triangles are identical to each other

I mean, yes and no.

Heavier objects have a higher “max speed” that they can fall at, compared to lighter objects. The acceleration to that relative speed is constant though. More or less.IE : While a bowling ball and a ping pong ball might start falling at the same initial rate, eventually the bowling ball will fall faster.

In a medium, which is an important distinction
bizarroland@lemmy.world 7 hours ago
Yeah, it’s not like they just blindly accepted what he said. They held up a feather or a leaf or a sheet of paper and a lead weight and dropped them both at the same time and the lead weight hit the ground while the leaf was still fluttering in the wind.
Empricorn@feddit.nl 8 hours ago
That’s not because of weight though. That’s just one thing being affected more by air resistance. In a vacuum, there would be no difference. In fact, they did just that during the Apollo 15 mission on the moon using a feather and a hammer:

Hey buddy! I came to post that video!
I know what is happening. I know why it is happening. My brain is still screaming at the feather to slow down.
NoneOfUrBusiness@fedia.io 7 hours ago
The acceleration to that relative speed is constant though. More or less.
It's not. Air resistance will affect lighter objects more due to Newton's second law and the square-cube law, resulting in heavier objects accelerating faster than light ones. Only at the initial instant, where there is no air resistance due to the speed being 0, will two objects of different weight be subject to the same downward acceleration.

It’s how Arthur fell faster then Fenchurch. He was heavier.

People have mentioned air resistance but the four elements also works as a model of the states of matter.

Due to air resistance, heavy objects do tend to fall slightly faster in atmosphere.

Take a balloon, fill it with air and drop it from a plane next to say a brick. The balloon may not hit the ground for awhile, especially if it gets caught on some air streams

I am most certainly not a science whiz but it’s so goddamn funny to see this whole comment section full of people just… explaning and correcting each other poorly with varying degrees of correctness. Just like 50 half-true and misremembered tidbits from everyone’s intro to high school physics class, blindly seeking targets in space. I promise you guys, there’s a very straight answer to this like two or three clicks away, written more clearly and succinctly than anyone here is managing to do.
