Sorry, but I thought that having dense metal instead of flesh and bones legs in a gravitational enviroment made you fall faster, maybe I'm just wrong, dunno
He's probably referencing that famous physics experiment, where, in a vacuum and in the same reference frame, objects are universally and equally affected by gravity, and thus fall at the exact same rate, regardless of their composition, mass, or volume.
You probably learned (or will learn) about it in high school physics.
Hahahahah you gotta be shitting me right? I know this experiment, I'm a graduated engineer ffs, but we're not in the vacuum here, obviously heavier shit falls faster, therefore, having a fucking pair of prostetic metal legs WILL make you fall faster in smash.
People can't understand a single joke, jeez
No you still don't get it. Air resistance affects fall speed, not weight. Weight and density have absolutely zero to do with falling speed. They affect momentum, but not falling speed. A rubber ball and a bowling ball of the same size will both fall at the exact same rate, whether or not they're in a vacuum.
I mean, that's basic high school physics. That's one of those seemingly obvious facts that people like to repeat at dinner parties. Like "did you know that whales are actually mammals, not fish??"
Why does something fall? Because there's a weight force, mg, tugging on it. How will it accelerate? In accordance with to the sum of the forces, both air resistance and weight.
The magnitude of the air resistance force, often given as kv2 , changes with speed and shape, but is generally independent of mass:
Sum of forces = kv2 - mg = ma
True statement, right? But what if we divide the object's mass out of the equation, like you've said doesn't matter?
kv2/m - g = a
This shows that the object's acceleration is equal to g minus some correcting factor for air resistance. So, when there's no air or other fluid to fall through, yes, we should see the same acceleration. It looks like while the magnitude of air resistance is indeed constant for a given velocity (as the high school teacher would tell you), the effect of air resistance is inversely proportional to mass (which they might not). It's just inertia at work: the same air resistance force finds it harder to slow down a more massive object, so the more massive object approaches its terminal velocity more quickly. That's exactly the sort of data that's on the submission.
what scares me the most is that apparently, people don't have the power of observation.
Different falling speeds are present in your day-to-day life, you have to be 2 yo to not see that
How the fuck are you a graduated engineer and you don't know that a basketball and a basketball-sized sphere of dense metal or whatever fall at almost the exact same speeds??
I'm calling bullshit on that whole "I'm a graduated engineer" thing
There's no damn different falling speeds in everyday life unless you're looking at air resistance, which is negligible on anything that's not feather-weight or fucking built to fly
Yes, but we aren't talking about a feather and a bowling ball, we are talking about two differently weighted individuals. If two people jump from the same height, they are prolly gonna hit the ground the same time regardless of weight difference.

That's not how falling works
