moon tidal effect?

Question

i understand how the tidal effect works, but does this work on all water or just large bodies? like does it effect the water in my body.

Answer 1

It's because of the Moon's gravitational pull. That simple.

Answer 2

Tidal effects occur because there is a difference in the force of gravity across each side of a body. Taking the earth as a whole the gravitational pull on the water on the near side is so much, that on the earth a bit less, and the water on the other side a bit less still, this causes the near side to constantly be pulled towards the moon and the far side to be left behind a bit (hence two tides per day). Note that this occurs becuase the oceans are large and have a gravity gradient across them. The medeteranian has small tides because it is reliveley small.

Small objects exhibit measureable behaviour dependant on Tidal forces, eg Volcanoes, Guysers. This is because tidal forces effectively modify g (the apparent gravitational force)

The tidal effect on your body is that your head will be slightly lighter than it would have been otherwise when the moon is overhead or underneath. This effect is minscule.

NOW NOTE If the earth were totally spherical and had a constant depth ocean all over it the tidal 'bulge' would be only a few cm. Tides are essentially coastal effects where this small bulge builds up in shallowing seas (like the recent tsunami).

Tidal forces are NOT LIMITTED to water. The potential of tidal forces can be observed on Jupiters inner moon Io. The tidal force is so great that the whole moon tends to be forced towards an elipsoid shape (pointing at jupiter all the time), as the moon rotates the bulge moves round causing constant earthquakes and volcanoes to go off as the crust flexes under this force.

BLACK HOLES (except supermassives) will exhibit extreme tidal forces as you approach the event horizon, this will ceertainly effect your body water, along with the rest of your body.

Answer 3

The force of the moon’s gravity pulling on a body is given by Newton’s Universal Law of Gravitation: F = G(m1m2/r^2), where G is the universal gravitational constant, m1 is the moon’s mass, m2 is the body’s mass and r is the distance from the body to the center of the moon. The distance from Earth to the moon is about 30 times the Earth’s diameter, so the moon’s gravity is about 7% stronger on the side of Earth facing the moon than on the opposite side of Earth. (31/30)^2 = 1.07

The sun’s gravity pulls on us about half as hard as the moon’s gravity, but the distance from Earth to sun is about 11,733 times Earth’s diameter, so the gravity is nearly the same on both sides of Earth.
(11733/11732)^2 = 1.0002

Correction: How many of you caught that glaring error? After looking up some facts and using a calculator instead of picking numbers out of the air, I have determined that the sun's gravity pulls on Earth about 18 times harder than the moons gravity. The solar tidal forces are therefore about one fifth as strong as the lunar tidal forces.

Since the moon pulls harder on the near side of the ocean, and less on the far side, the ocean gets stretch out, with high tides on the near and far sides and low tides in the middle. When the sun and moon work together (new moon and full moon), the tides are bigger; that is called a spring tide. When the moon is in the first quarter or last quarter, the solar high tides coincide with the lunar low tides, so the tides are smaller; that is called a neap tide.

The moon’s gravity is practically the same on opposite sides of the biggest lake on Earth, because both sides are practically the same distance from the moon. So, yes, there is a tide on a big lake; but it is much too small to detect.

The lesson is that the moon pulls bodies of water toward it through a magnetic force. That force is effective on water because it is not held down by a human body, or cement, or nails, etc.

As for our body fluids, they are safe. They are neatly tucked inside our body which cannot be pulled toward the moon because of gravity. Gravity cannot hold every drop of water, so it is pulled, then dropped back into the sea. This recipricating action is what causes tidal waves. The sea cannot be pulled into the sky because of its density, but the surface is distrubed by the moon's magnetic draw.

Answer 5

All objects of mass pull on all other objects of mass.So every celestial body pulls on every other.So in theory all of the planets and moons and our star are effecting the planet and its inhabitants.Answers above give you facts and data to prove this. Lunar-tic is associated with full moons or rather the passing of the moon overhead,ask any police force about crime rates at this time and they will tell you it increases.So some cause and effect is very evident.Have you ever noticed Animal behaviour change too?

Answer 6

the gravitational effect by the moon and sun on the earth is always present, however it is so small that we don't even notice it. So therefore it does affect the water in your body very, very slightly, but since the oceans are huge, there is a much larger effect seen.

Answer 7

OK, you know that tide is due to the moon's gravity (and sun's a little bit), but that affects everything, not just water, not just liquids. For example, you actually weigh a tiny bit less when the moon is overhead, because it is pulling you upward.

In principle, your head is affected more than your feet, because it's closer to the moon. But my goodness, that effect would be hard to measure!

Answer 8

They'll keep getting longer until the Earth's rotation slows down to the point that Earth and the Moon become gravitationally "locked" where the Earth's day will equal the length of a moon revolution. Both will keep the same side facing each other - the same way the Moon always keeps the same face to the Earth.

Answer 9

no. the reason the moon affects the tides so much is that the center of mass of the earth/moon combo is below the surface of the earth.
so as the moon goes around the earth the amount of ocean water above / below that center of mass point changes. that change adds significantly to the minisule change in weight.
the center of mass of the you/ moon system is way back next to the moon. so the only effect you feel is a change in weight of about 1/250billionth of your average weight.
asfor lakes, they would have to span enough of the earth's surface to have significant water above and below that center of mass

Answer 10

It affects all large bodies of water, not just seas and oceans. There is some evidence that it affects our moods, probibly for the same reason.
