Tides Definition and 74 Threads

I am having trouble rationalising the fact that the moons gravity is a fraction of the Earth's and is far out in space, but still manages to out pull the Earth's gravity albeit a tiny amount and create tides?

I have a question about tides. I just read an article that states tides are influenced by the moon, sun.planets and stars. I have no problem with understanding the moon and sun, maybe the closest two planets, but the stars??! Does anyone know if that is factual and if so, how is it? Thanks

Homework Statement I have 1.805cos(2pi / 12.165x) +3.125 as the function of tidal data. However I need to use another function, superimpose, to more accurately graph the data for the tides. And yeah I'm pretty lost... Does the next function have to be something to do wit the moon and its...

I'm having a bit of trouble working out the cosine function for the data I have on tide charts. Homework Statement I need to put the data provided into the cosine function y=acos(nx-b)+c Morning average high tide: 5.137 metres Morning average low tide: 1.29 metres Afternoon average high...

Please help me ya'll. "If the moon was twice as far away from the Earth as it actually is, how would tides be effected?" Any ideas/answers? Thanks!

Homework Statement The gravitational attraction of the Sun and Moon on the Earth produces tides. The Sun's tidal effect is about half as great as the Moon's. The direct pull of the Sun on the Earth, however, is about 175 times that of the Moon. Why is it that the Moon causes larger tides...

Homework Statement What three gravitational forces act on the oceans of the Earth to cause the tides? The Attempt at a Solution Hi. I was wondering if anyone could help me with this question. Everyone knows it is the gravitational force of the moon, but that's about it. :frown: Could...

What part of the theory of general relativity helps us understand why we always see the same side of the moon? Thanks.

I have been trying to understand how our ocean tides work and read about the effect of our moon's and sun's gravitation. I have learned there are diurnal, semi-durnal and mixed semi-diurnal tidal patterns When the moon is directly overhead equatorially (near side), I've seen illustrations...

If ocean levels go up enough, will they have an impact on the Earth's rotational speed and the Moon's orbital radius? If so what will the effect be? It seems that all these things are tide to one another.

Hello and thanks in advance for any help you can offer. I really appreciate it. I am learning about tides and having some trouble here: “What would be the effect on the Earth’s tides if the diameter of the Earth were very much larger than it is? What would be the effect if the Earth were as...

I read the book and looked through some sites but I don't seem to understand. I have a lab soon and I have to answer this question. What must be responsible for the pattern of tides that you see? Why? a. The moon orbits the Earth once each day. b. the Earth spins on its own axis once each...

Bush's approval rating has been dropping steadily for months now. At 34% approval, according to the latest http://online.wsj.com/public/article/SB113216347138199155-5Z1Ri_om8ITUbV_jD2bx6maguMY_20061116.html?mod=tff_main_tff_top poll, even once strong supporters are unhappy with his performance...

Hi all, I am reviewing for my final and cannot seem to find how to solve the following If the tides on Earth one meter high how far away is the moon? What equations should I use to calulate how the moon effects the tides on earth?

Morning everyone! I was up late a few nights ago and I noticed how large the moon looked in the sky. Being a creature of habit myself, I began to wonder why the moon controls the ocean tides. I've been thinking about it and I couldn't come up with an answer. The moon controls the tides. Thats...

It is said that the moon's tidal forces on the Earth create differential torque which causes a slowing of the Earth rotation. It is said that this causes the moon to increase its radius of orbit. The remarkable result is that rotational energy of the Earth is transferred to the moon to increase...

Symon, Mechanics pp.174: "The effet of lunar tide is gradually to slow down the rotation of the earth. As the angular momentum of the rotating Earth decreases, the angular momentum of the moon must increase." Why are the lunar tides gradually to slow down the rotation of the earth? (I assume...

Why isn't there a more pronounced effect from the Sun on tides? The distance from the Earth to the Sun seems negligible considering the mass of the Sun. While typing this out and thinking about it, the most reasonable explanation I can come up with is that the Sun has so much mass that the...

Ok so I'm reading up on some physical (no that's probably not the right word, enlighten me!) phenomenas in this case the tides. So as far as I've understood the water on the surface towards the moon is affected both by Earth's gravity (which is bigger) and the moon's, and therefore positions...

One of my homework problems for GR says: "Explain why a uniform external gravitiational field cannot raise tides on the Earth." My explanation is: Because of the large size of the Earth compared to the distance the Earth is from the moon, the nonuniformity of the moon's gravitational...

I know the moon causes tides, but I am unsure why. I did a quick calculation and found that the sun has a greater gravitational effect on the Earth than the moon does. My question is, how come the sun does not affect tides despite the fact that the gravitational force is stronger than the moon?

No one answered my burning questions about imaginary tides...these tides that have me in a bind, so to speak. So, *sniff, sniff* I will just blunder through the essay questions as best I can. Thanking everyone who has helped me all these weeks...I have a test Monday and feel confident...

Tides due to the moon vs. the sun? The acceleration of gravity on the Earth due to the sun is 177 greater than gravity on Earth due to the moon. Why are the tides predominantly due to the moon and not the sun, in spite of this number? Nautica

Hi There is a question in my physics book that kept me thinking but still can't find a solution... here is the question: The Moon is observed to keep the same side facing the Earth at all times. If the Moon had oceans, how much time would elapse between it's high tides? since we know...
