Essentially, Yes. The Barycentre is the balance point of the system. The orbital angular momentum of the two objects around this point is balanced against the gravitational attraction between the two objects. There is a very simple equation, which allows us to calculate it's location, but you'll have to comment on my cartoon find out. You would be very welcome. Thank you.

Barely visible you say. Well how do you account for the increase in sun spot activity, which occurs on the same 11 year cycle, when Saturn and Jupiter are on the same side away from the Sun?

The existence of the barycentre is not a theory. It is an established fact, in exactly the same way as gravity is perceived as the attraction between objects of mass. This is true. The Earth and Moon both *orbit* around a common centre of gravity, they do *not rotate* around the barycentre. The distance between the Earth and Moon is not fixed, because Johannes Kepler's first law of planetary motion states, that all *orbits are elliptical.* That is why there is a variation between a total and annular eclipse. Does that answer your question about how the distance between celestial bodies varies over time? The concept of the barycentre is logically established, through the generally accepted laws of orbital mechanics. As set out by Sir Isaac Newton, Johannes Kepler and Galileo. All formidable scientists in their own right.

Nice Voice too

Thank you

​@@bhanopersaud1984 Hello Bhano, I get the distinct impression that the wonderful teacher here, is behaving rather modestly towards your nice comment. Can I just politely suggest on their behalf, that you also view their video on the barycenter as well, because that will complete your ideal picture of our daily tides. Good luck.

Who on Earth told you, the moon has no gravity? 😂😆🤣 The acceleration due to gravity at the surface of the Earth is 9.8m/s^2. The acceleration due to gravity at the surface of the Moon is 1.6m/s^2. Therefore, the moon's gravity does pull on the earth's oceans, but that's not the end of the story for tides, and only the beginning. Good luck in your exams? 😂😅

Hi Nashiira, I'm guessing from your polite comment that you actually meant *revolution* not *evolution* ? Revolution - describes the motion of a planet in orbit around a barycentre, which is explained in a delightful little video released by Bright Side Science some days ago. Evolution - is a theory proposed by Charles Darwin in 1859 and was called, On the Origin of Species by Natural Selection. Newton and Darwin were both extremely great scientists. Take care and thanks for commenting. 👍

​@@nashiiranash You are very welcome, Nashiira. 👋

No!

If you really want to understand in depth about this topic, you should learn about a very much important topic called ' barycenters'. I apologize for missing that content in this video. But a video regarding the same will be released as soon as possible.

There is absolutely no need for you to apologize 'Bright Side,' although your diligent and thoughtful behaviour is very noteworthy, and as any respectable scientist or teacher will tell you, it's vitally important to show humility in the sight of small errors, and it's best to just make the corrections, and move on with your work. Your tides presentation is a perfectly valid explanation for the simple occurrence of two high tides a day. At no point did you say that the gravitational force of the Moon was higher than the Earth's. Instead you said that the centrifugal force counterbalances the gravitational force and causes a high tide on the side facing away from the moon. Perfectly correct. The Centrifugal Force was an idea introduced by Newton himself, to explain the 'apparent' outward movement of an object in circular motion, very similar to the action of a centrifuge, but he had to conclude that it wasn't a 'real' force, because there wasn't any agent to produce the desired effect, very similar to the action of gravity, which is the 'apparent' inward movement between objects of mass. However, when questioned on this apparent error in his calculations, he had no answer and said, _"I'll leave that for the consideration of a future scientist?"_ And, that bright side scientist was none other than Albert Einstein, who concluded that gravity and centrifugal were both _'apparent'_ forces, which only appear in an accelerated frame of reference, and that both have a contributing factor behind the tidal phenomena we observe in our oceans, lakes and seas. Can I politely suggest you have a look at Dr Becky's explanation of tides, as it's very similar to yours, and might provide you with some inspiration. Good luck.

Well, can I wish you the best of luck on behalf of 'Bright Side Science.' I'm positive you'll do great, and just remember, if anyone asks you where this centrifugal force originates from? Then, tell them that the Earth and Moon both orbit around a common centre of mass, called the Barycentre. Good luck.

Most welcome 🤗 and Best wishes ☺️

All the best

That is a very good question, and I'd like to attempt a very simple answer for you, which hopefully you'll let me know whether it's good enough or not? Roughly speaking there are two high tides a day, caused by the moon. However, when the sun and moon are roughly aligned, during a new or full moon, which occurs once a month, then those high tides will be slightly higher, and we happen to call them spring tides. I hope that was helpful, but it's quite difficult to illustrate, without a diagram. Good luck.

​@@wavydaveyparkerquit posting your flat earth nonsense as being valid science. The tides are not caused by the moon but by the earth's motion around the sun. The earth, spinning on its axis as it orbits around the sun creates a clockwise acceleration event and then a counterclockwise acceleration event. High tide is caused by the earth reaching maximum velocity it orbits the sun in an elliptical path according to Kepler's laws of motion. This event occurs the first of the year when the planet is closest to the sun with High tide on the OPPOSITE side due it experiencing a higher rate of acceleration at that point. Newton's and Kepler's Laws of Motion are what describes the tides. Not your junk flat earth science.

I didn't tell anyone as I understand everything. This video is based on the ncert syllabus for small school children.

​@@brightsidesciencePlease try and ignore the criticism, This individual is just attempting to be annoying and is very confused, Your video is a perfectly adequate explanation for daily tides, and Ideal for helping young people to understand. This person has just misunderstood the difference between *axial* rotation and *orbital* motion, it's an easy mistake to make. The gravitational and centrifugal effects of motion around a common centre of mass, or on its axis, both contribute to the tidal force envelope in a Newtonian model of gravity. It which gravity and centrifugal, can both be considered as forces in a classical interpretation of Physics. Thank you again for your diligent approach to science education. Take care.

@@wavydaveyparker It’s hardly adequate if it teaches someone, even at a young age, something incorrect. The fact that you, presumably an adult, also believe the second tide is caused by “centrifugal forces” despite all logic showing this to be ridiculous shows the danger. You end up with an ignorant adult.

@@annoyingbstard9407 On the contrary, it's perfectly adequate if it teaches someone, even at a young age, that the Inertial motion of our planet through space is a contributing factor to the tides. If you'd actually read my comment and understood it, assuming you're an adult. You might find that I never said the second tide is caused by centrifugal "forces" but it's perfectly fine to call it a "force" in Newtonian Mechanics, and I wouldn't call Sir Issac Newton an ignorant person, because I'm sure he'd agree. However, if you have an alternative explanation that describes the motion of planets in a non-uniform gravitational field, then I like to hear it, and let's stop with petty insults, and remember to keep it understandable for the young audience who are studying the ncert syllabus mentioned above. Good luck.

@@wavydaveyparker Thank you but it appears you’ve decided you’re right so let’s leave it at that. As for teaching the kids anything, even if it’s incorrect, because it’s good enough for them….I’m happy you’re not an educator and let’s leave that there too.

No straight line acceleration in space. The tidal force is not a pulling force, it’s a pushing force, outward from the centre of the earth in the case of the sun and moon, or for the example of an object in rapid orbital _inertial_ motion around a black hole. As illustrated in this correct tidal explanation. The gravitational and centrifugal effects of motion around a common centre of mass, both contribute to the tidal force envelope in a Newtonian model of gravity. It which gravity and centrifugal, can both be considered as forces in a classical interpretation of Physics. Was that helpful in any way? Thanks

@@cybermonkeys : Thank you for the pains taken and for your time to explain. Let me be honest that I could understand a little . The blame rests with my limited brain!

@@kmrao8528 On the contrary, that's just not true - You're brain is perfectly fine! You recognised and identified a fundamental question in Physics, which has confounded many great minds since Newton. Even Mr Einstein himself had immense difficulty finding a correct solution. So, you're in very good company - Keep going! The only failing here, was that my dumb little brain wasn't able to explain it to you better. If you can find my friend @wavydaveyparker cartoon, then maybe we can work through it together? Good luck and happy new year.

congs

Thank you! 😃

nah bro

The earth is orbiting and revolving. The ocean is always on the move. You, me, the earth, the oceans, and the moon, are never static in space. The moon doesn’t have to be directly overhead to cause a high or low tide. Did that answer your interesting question?
