Ocean's Tides Explained

The oceans on the earth's surface are attracted to the moon through the effects of gravity. Because the strength of the gravitational attractions depend on the separation distance of objects, the oceans on both sides of the earth, as well as the earth itself, experience different gravitational forces towards the moon, causing two oceanic bulges which result in two high tides daily.

The video also explains why tides as well as moon rise and moon set are 50 minutes later each day, based on the moon's orbit around the earth.

About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students .
We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program.

Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class!

The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival.
It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences.

Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth.

The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world.

Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths.

Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

that explanation is not true purely. moon and earth are orbitting around each other, and the barycenter is in earth. so earth is swaying around this causing a orbital velocity inequality. the far side from barycenter on the earth is speeding with a high orbiting velocity, so centripedal force causing antigravititational effect and there gravity decreases. so water tides up. same thing is viable on moon, but more antigravititation would become. (this effect is very little on earth, 0.027m/s around barycenter causing 6.91*10^-8 m/s^2 centripetal acceleration, moon's gravity on earth is about 3.32*10^-5 m/s^2)

[WAGNERMJW]

The assertion of the far side high tide is illogical. It's not as if the ocean is an independent and static object floating inside a water balloon such that the earth can be pulled back and forth while the ocean stays largely static and unaffected by gravitational pull. When the moon pulls at the ocean on its near side it is also pulling the ocean to flow around the earth toward it, thus causing the bulge, the high tide. It's not that the moon is pulling the h2o molecules apart from each other on the near side causing the bulge, at least not measurably. It's because there's more water that's been pulled toward the side facing the moon.

[ronsemneck]

If the forces shown in the cartoon were the only forces acting, then the points A, B, and C would have different accelerations, and the earth would soon be torn apart. So, this is not a good explanation for tides. You Failed the test.

[hanifhanif]

While explaining the TWO TIDES, How the Point B ( earth ) moves towards the Moon.... ?? This will create Gravitational imbalance and Earth and Moon will merge and Destruction and a second Big Bang!

[tempus.narrabo]

So many unanswered questions, right off the bat, what's stop the pull of the earth and moon?

Same pull? The moon is supposed to be 1/3 size of the earth, earth surely would have more pulling power, mass?

[suharins]

If moon pulls ocean toward itself. Then why it can pull rain droplets toward the moon. And if fill balloon with water and place it on flat surface it will roll toward moon?

[jayjeetnandi]

But at the point C there is centrifugal force which balance it I think 🤔

[pascalstriangle]

No. Logic failure. Your example of “moon on the right, creating a high tide on the left” with your rationale being that, the “earth is pulled away from the water and towards the moon” fails both logic and physics. The southern ocean is not anchored to something, so that the earth can be pulled away from it. Whatever gravitational pull the moon has upon the earth, it also has on the water, such that the water should, can, and does, flow in both physical and density terms, cyclically chasing the source(s) of the extraterrestrial gravitational pull, in constant marginal distribution of the majority of the oceans. And volumetrically toward the source(s) of gravitational pull. Therefore, the high tide on the side opposite the moon is due entirely to a gravitational source on that side, or from some as yet unknown, physical law or power offsetting the moon’s weaker gravitational influence. The earth does not move towards the moon in a straight line.

[maxwang]

2:40 This explanation of two high tides a day is really bizarre - or beyond comprehension to me. The moon is dragging the earth in the middle of a ball of water with a bulge!

[jebythomas]

Sir I have doubt. Is there any effect of centrifugal force at the POINT C

[hansdegroot]

Mmm ithe tidal differences are the same here in holland at least more, than 1.93 meter on a calm day but i was in denmark itcwas less than 30 cm difference. Very strange. I checked. It was realy open sea and they did not have dunes or any ithe barriers to block high tide.

[pillarsofhercules]

Scusa, non è così che funziona la gravità e non è così che vengono calcolate le maree e i tempi delle maree.

[eitidbt]

A perfect description of tides. Thank you. Well actually, it’s only correct, if you’re name is Aristotle (circa. 384-322 BCE) and you still believe in a flat earth and the geocentric model? Fortunately, science has come on a long way since then? Sorry nice try? Please refrain from using outdated information and keep up with the recognised curriculum taught in present day schools. Thank you.

[pennywise]

You are actually not correct here, because this common explanation is completely wrong. If it were the moon pulling water towards it, tides would only go up on the side facing the moon accumulating at the point nearest it. It’s more like the Earth’s centre of mass is squeezing all the water towards its centre. Thus, the pressure of this squeeze is least at the line made by the Earth’s centre of mass and the moon’s centre of mass. That is why it bulges on both sides. Imagine your hands on either side of a balloon pressing together.

[Doruc]

Gravitational force of The Earth and the Moon are opposed.
Moon's gravitational force is 6 time weaker than Earth"s. So, should be no gravitational attraction from the Moon. The Moon is not "falling" on Earth because of the rotational speed of Moon, "Centrifuge force" that nullifies the Earth's pulling force of the Moon towards the Earth. Comments?

[andybrownen]

The information you give about the cause of the ocean's tides is incorrect. The two ocean bulges are of equal size (equal resultant forces on both sides of the earth) and your explanation of their cause, while convincing, is wrong. I suggest you research 'Gravity and Tides'. The cause of the second bulge can be explained by the Earth-Moon system and the resultant shift in the centrifugal force acting on the oceans.
Best wishes,
Andy Brownen

[natecote]

Dude the more I look into this the more I feel like it's all bs and makes no sense! If the moons gravity is soooo strong it pulls our entire ocean towards it why doesn't it affect us? Why can't I jump higher at certain times of the day? Why doesn't the tide change with the earth's tilt?

[oneeleven]

‘This is not only not right, it’s not even wrong’ Wolfgang Pauli’s quote fits perfectly here.

[xtian]

How does the earth turn into the ocean when the ocean is in the earth? The planet is not surrounded by the ocean. Im really confused with this explanation. This explanation only makes sense if the earth is flat.
