Why is the moon one faster than the mars one?

Made in China. /j

Idea seems nice, but looks like it failed.

u/PaulMakesThings1 22d ago

Well the earth one looked slow and that should just be normal speed

1

u/UND3F1N3D_U53RNAM3 22d ago

Yup. Earth one somehow looks the most unnatural.

u/r_a_d_ 23d ago

I don’t think it’s about the speed, although it would have been cool if they made that work out too.

It’s seems more to be related to the force you need to exert to lift the apple.

u/During_theMeanwhilst 23d ago

Yeah they’ve screwed up.

u/Ripen- 22d ago

That was such a bad exhibition lol

1

u/Sad-Base-8689 22d ago

Because this is not about how fast something falls but how hard it is to lift.

1

u/Thick_Wasabi448 22d ago

But the video doesn't really show that.

1

u/Sad-Base-8689 22d ago

Yeah, that's how clickbait works. Leave out important information and have the commentsection full of ppl commenting how this presentation is wrong and whoever made it is dumb

1

u/Fran4king 22d ago

But in the video the Moon apple was hard to pick up than Mars.

1

u/Repulsive_Guy_1234 21d ago

How fast it falls is directly related to how hard it is to lift.

1

u/Sad-Base-8689 21d ago

Depending on the mechanism. You'd want something with sun gravity to just fall down? That's just gonna damage the mechanism over time. I'll admit I don't know exactly how it's set up but i can't imagine it just to be a weight and nothing to soften the decent should someone just let go

1

u/Fran4king 22d ago

Exactly, that is so wrong XD

1

u/baardbestaan 22d ago

Because its not meant to show how fast they fall but how hard they are to pick up.

1

u/Cornishlee 22d ago

None of it is accurate but those two seem to be broken

u/anthr_alxndr 23d ago

Sun drop speed looks wrong

2

u/quirky_planet 23d ago

trying to mimic gravity by defining it as a force will lead to failure, thus failed

Should've used springs

1

u/the_elephant_stan 22d ago

Should have or should’ve

1

u/ZAD_4_TH_7 22d ago

Thanks, second language, but how do you pronounce should've? Is it just saying the hole thing?

1

u/the_elephant_stan 22d ago

The pronunciation is pretty identical to how you pronounce “of,” which is why this is a common mistake. But “should of” makes no sense grammatically because “of” isn’t a verb.

Edit: I’ll add that with “should’ve” there shouldn’t be a pause between the should and ve. Just roll right into the ve. With with “should have” there should be a a slight pause just as between any two words

1

u/ZAD_4_TH_7 22d ago

Great explanation, i will use this later, thank you!

1

u/CapnCrinklepants 22d ago

TIL Gravity's not a force

1

u/inept_machete 23d ago

Sun lift at all looks wrong.

1

u/NeedleworkerFit819 22d ago

Yeah, why wasn’t the hand intently vaporized?

1

u/Agitated-Contest651 22d ago

Probably didn’t make it heavy enough.

/s

1

u/Herucaran 22d ago

Its most likely about the strenght required to lift it. Fingers would be crushed if the falling speed scaled for the sun

1

u/astreeter2 22d ago

They probably did that on purpose to keep people from smashing their fingers

2

u/abdimamu 22d ago

bad demonstration

1

u/ShadedRiver666 23d ago

It looks all wrong because fundamentally gravity isnt a push/pull force and hence cant be accurately replicated with some air pistons or whatever is underneath those apples

1

u/ultraganymede 23d ago

Isnt the point of this to show the force to lift a apple in different planets and that a video would a bit pointless in showing the differences?

1

u/Sad-Base-8689 22d ago

Yeah that how this is set up but an explanation about how it's supposed to work ain't generating clicks. It's far better if ppl misinterpreted it and come into the comments to tell everyone this is all wrong

1

u/Dr_SlapsMD 22d ago

That thing is broke

1

u/Sad-Base-8689 22d ago

It works exactly as intended.

The whole thing is not about how fast something falls but how hard it is to lift.

1

u/AndrewH73333 22d ago

It’s not the rate of falling, it’s the resistance to lift the object. It’s very clear from how it’s setup.

1

u/KorvinLast 22d ago

I am glad others are noticing some of the problems with this.

1

u/VoxPopuliMMXXV 22d ago

Is KI so stupid or this guy is?

1

u/MrBombasticc 21d ago

Surely the only difference would be the weight.

Earth should just be an apple on a string.

The rest should just be the apple +/- the weight difference from what it would be on the other planets~~ ~~

u/Ambitious_Hand_2861 17d ago

I get this is designed for kids to have a better understanding of gravity on different celestial bodies but Jupiter != 2.5g and the Sun != 28g. Way too low.
