I TESTED a NASA Apollo Lunar Gravity Experiment!

[@WHO_ACTUALLY_CARE]

Thanks math and science i wanted to learn more about gravity

[@Chunkypooch]

Yay! I think I’ve been watching your videos since 2019 when I just got my GED and first applied into college. Now I am a registered nurse. I love how your channel has evolved! You have always been one of the greatest teachers.

Galileo and NASA have demonstrated something, but they didn’t test the original hypothesis (from Aristotle). If you carry an object to the top of a tower, then the earth’s center of gravity will move slightly in the same direction as the object. Therefore, the time for it to fall to the surface decreases by a tiny amount. The effect is greater for an object with greater mass. It follows that, objects with greater mass will arrive at the earth’s surface in less time than objects with less mass. Obviously this effect is minuscule, so we can’t measure it in practical applications. Yet that shouldn’t trouble physicists who are comfortable analyzing actions that take place within a trillionth of a meter (or less). If (like Galileo) one carries two objects to the top of a tower and drops them simultaneously, they both contribute jointly to the shift in the earth’s center of gravity, so they will hit the ground at the same instant. A true test of the hypothesis would involve carrying the two objects to the top of identical towers on exactly opposite sides of the earth, then dropping them simultaneously. Under those circumstances, the heavier object would arrive at earth’s surface in less time than the lighter object (by a tiny amount). All of this speculation began with Aristotle. He didn’t specify a tower, simultaneous drops from the same tower, or other issues. However, Galileo, modern physicists and NASA concocted experiments that are incapable of testing Aristotle’s hypothesis. Why? Because (a) their simultaneous drops tests are easier to perform, and (b) they don’t understand gravity beyond their quantitative representations of it.

You have an interesting thought experiment. A few issues in real life, 1 is that the Earth isn't homogenous, local gravity is different everywhere as the mass distribution depends on the rocks under you and composition of the mantle under you, if you want to nitpick you are heavier after it rains. 2 how do you isolate the influence of Earths gravity from the Moon and the Sun's gravity, they would add on one side of Earth and subtract from the other. 3 the Moon and Earth orbit around a common barycenter that is about 1,000 miles below the surface, the opposite side of the earth gets flung out (why we have another high tide on that side as well). You would have micro changes from charge build up on you test objects compared to electrostatic buildup in the atmosphere, magnetic field influences. You have buoyancy in Earth's atmosphere if you do this not in a vacuum. The list never ends, you would never isolate everything. However your 10 pound ball wouldn't raise Earth's center of mass by even 1/100th the diameter of a proton so I wouldn't worry about it. What you should be worried about instead is how much you slow the rotation of the Earth every time you stand up and then speed it up again when you sit back down. It's very annoying.

[@mrraspberry8263]

Nice to see you still active ❤

[@saifurrahmansaadi]

Thank you

[@saftheartist6137]

May you talk about the physics of shadows and reflections.

[@tresajessygeorge210]

THANK YOU... SIR...!!! It is very good... and I would like to learn more about such topics related to physics, chemistry, molecular biology and its connection to nature & universe also quantum dynamics and computing...!!! The pace in which you are giving the lectures and explanations with practicals are excellent and helpful to curious students like me ( a retired critical care nurse... who has been studying multidisciplinary subjects including science, history, evolution, genetics, molecular biology...Theory of everything etc ... etc for more than five years ) ...!!! THANKS AGAIN... I am fortunate to have the chance to learn from you SIR...!!!

[@jeshuamathis9013]

I love the experiments. I’ve been wondering how to use the things I learn here. Appreciate your work 🎉

[@shahrezoya3143]

Sir I want to know about Quantum physics.

[@surajshukla6813]

Wow sir this explanation was so best ) . Actually I understood the whole concept.

[@AmericanFaction]

Thank you, math and science 🙏🙏🙏🙏

[@ArazKaraoghlaniancom]

Thank you Mr.Jason , thank you For your Hug effort for teaching Us new topic , i would like to understand basics of Artificial intelligence

[@sundaramguruswamy5490]

Every Matters taken from earth and put from 10 meter height Earth is pulling.why ? According to theory elevate because same poles .so do the falling object should rotating same earth RPM should replace I mean elevate.magnetic(electrical theory).

[@jevonjohnson5797]

Much thanks sir

[@shah5]

if you hang something on a scale, and drop it from a height, will the weight of the thing reduce to zero or will it be the same?

[@andreajimenez6601]

Thank u so much for u helping with this math I so appreciate it God bless

[@deholin7110]

牛頓第二定律F=ma是物體處於理想的靜止情況下的動量、質量、加速度關係式，其中加速度並不隨時間累積；而鐵鎚和羽毛分別受星球重力加速度的墜落實驗，重力加速度隨時間累積，係適用於牛頓的萬有引力定律。結論：顯然重物即鐵鎚（密度大）比輕物羽毛（低密度）先著地，只是不足兩公尺的距離過短難以觀察判斷先後而已！

[@deholin7110]

鐵鎚和羽毛早已經在星球重力場，它們的墜落實驗，不適用牛二定律。

[@UnknownUnrecognized]

thanks

[@nikis7742]

Sir I think it's not appropriate experiments as without air there is difference in time although very little but it matters it's like zooming circle perimeter to make it straight. If you do same experiment with very very long tube in vaccum there would be clear observation that there is time lag gravity of earth expands to thousands kilometer but experiments done are like zooming at infintesimal area only

[@contanimationnation8615]

Although I know this does not happen, after watching this I started pondering why the larger object (bowling ball) doesn't start slower than the golf ball but end up accelerating faster over time.

[@AlexanderMacNabb]

Anti-gravity field? Is it possile?

[@dianetheone4059]

Does-density-matter?

[@drumtwo4seven]

Nice 👍

[@hemrajue3434]

Does gravitational force acting on an object decrease as it moves away from the earth?

[@MathAndScience]

Yes absolutely.

[@wally7856]

Gravity follows the inverse square law. It decreases the same as the brightness of a light as you move away from it. As you move further away it gets weaker.

[@trevorbates8972]

I see gravity slightly differently. You see...we must take into account the high speeds involved in the Earth's universal motions. It spins on its axis...sails around the Sun...tours the Milky Way...rotates around a black-hole...all at very high speed. As a consequence the Earth digs a hole in the fabric of space, governed by its mass, which touches the static universe lying beneath this activity...hence the imploding force around the Earth we call gravity.

[@DrDeuteron]

So that implies an absolute restframe, and that violates relativity big time.

[@trevorbates8972]

Relativity is a property of the expanding universe...but before the big-bang it was a stationary, static universe, with many clouds of plasma just drifting around in a timeless zone waiting for the trigger that brought time, mass, electromagnetic force, and gravity into being.

[@Dr.Thunder-math-physics-series]

Good!

[@fallingsky1984]

Why did youtube add context to your vid ??

[@garybartnik1509]

Sir, if you could Remove ALL of the air out of the container, would the glass jar collapse??😊🎲✨️✨️✨️

[@DrDeuteron]

No

[@sampamnl.8964]

ขอบคุณมากครับ

[@Woodman-Spare-that-tree]

You’re overlooking wind resistance. I think it need two balls of same size but different weights

[@richardl6751]

Aluminum and steel but the results will be the same.

[@wally7856]

@@richardl6751 They won't be the same with air resistance, there is a reason parachutes aren't made with lead. The heavier ball pulls through that resistance with more force. Drop a beach ball and one the same size made of steel.

[@mathgirl4841]

So cool 🆒

[@BussinJohnson]

Gravity is a concept that does not exist, it's buoyancy, come on , you are smart enough to know that!

[@brandonbennett4970]

ur an idiot dude. have you ever read a physics textbook?

[@ashdri4105]

Can human survive the fall from 200 feet high in moom gravity?

[@kooros100]

Why Earth is pulling the Apple?

[@AmericanFaction]

Please, what is gravity itself? What makes it up to be called gravity?

[@michaelkurtz1967]

Sir Issac Newton named his force gravity after the latin word gravitas which means weight.

[@Yahs-our-All]

So the earth is flat

[@RyanVorobiev-x8d]

😂

[@JesusIsreal72]

So what can we learn by adding barometric pressure to the equation? By doing so will the equations only be good for certain specific geographic locations at specific times? Is it right to assume barometric pressures change, specific to the cycles of the earth's rotation and the current Jet streams? Babbling.. incoherently? LoL

[@jjsmallpiece9234]

But did you American's actually go to the moon? Wasn't it all done in Area 51? We Brits have other things to waste our money on.

[@fantastica5967]

From where u get all this shit

[@wally7856]

Like what?????
