Although gravity has been known to exist since people knew they could fall, it was not until. Moon Reader Pro' title='Moon Reader Pro' />Moon Reader ProIsaac Newton came along that a mathematical description of gravity was forthcoming. It was Newton. who showed that the force of gravity obeyed a simple algebraic equation, shown here as equation. Gm. 1m. 2 R2equation 1. In equation 1, Fg is the gravitational force between two objects of mass. R is the distance that separates the two. This equation is important because it is the fundamental equation for describing the. Newtonian physics. It is, however, an idealization it assumes the masses. But, of course, all real masses are not point masses, and therefore do not. Newtons equation. However, as an approximation the equation works very well. For instance, in analyzing Earths orbit around the sun, one needs to include the gravitational. Introduction to Tides. Moon Reader Pro' title='Moon Reader Pro' />A tide is what happens when the masses we see in equation 1 are not separated by. A tide is a differential gravity, the. In figure 2, below, we see how the tidal force operates between Earth and. Earth. As figure 1 shows, the force is not constant over the distance between the moon and the. Earth. The moon, being rather closer to the near side of Earth, pulls harder. I/41BVvk-95rL.png' alt='Moon Reader Pro' title='Moon Reader Pro' />Earth that is. In physics, we call this kind of effect a.

Earth and the moon, while the force seen in equation 1 is what keeps Earth and the moon in. As the red arrows in figure 1 imply, there is a inward pull on the. Earth, towards the equator, which would tend to squeeze the planet. Squeeze a rubber. Add to that the effect that the moon pulls harder on those parts of. Source Code Program Database Delphi on this page. Earth that are closer to it, and the result is that the Earth is squished, bulging towards. The effect is illustrated below, in figure 2. The illustration in figure 2 above shows the solid earth green and the oceans blue in. The solid Earth really isnt all that solid, and it does bend under the moons. Earth, and. so they will be much more deformed by the moons tidal squeeze. Hence, the bulge is mostly ocean. The gaseous atmosphere is tidally squished too, but it does not. I will ignore it here a detailed study of tides should not. I only do it here because it does not figure prominently in this. In a static system such as in figure 2, the mostly ocean bulge points right at the moon. But. the real system is not static the moon goes around the Earth, but the Earth spins on its daily. So the spin of the Earth pulls the bulge out in front of the moon. The result of this is illustrated below in figure 3, and we are now ready to understand the. Earth moon system. The ocean bulge is pulled in front of the moon by Earths spin since the ocean is. Earth, it has to go where the Earth goes. But it cant go too far. The result, illustrated in figure 3, is that the ocean. Earth and moon, while. Earth spins under the ocean. The ocean is gravitationally bound to the Earth, but it is. Earth the way a rock or a mountain is. There is an interface. Earth are free to move with respect to each. That interface, like any other real physical interface, is not totally frictionless, and. Friction force. But in this. Earth impede each other. The. ocean runs into the continents and has to wash around them so how they are distributed around. Earth makes a difference. Since the Earth is trying to spin forward, but the ocean is held back by the moon, the Earth. Just as you can feel the resistance if you try to. Earth feels the resistance trying to move through the water of the. Earth causing its spin rate to slow, and. But the Earth ocean system also exerts. B in. figure 3 is at an angle to the line that connects the center of the Earth to the center of the. As a result of that torque, the Earth also transfers energy causing its spin rate to slow. Earth. At this point we are ready to understand two important observations. First, the high and low. Earth moving through the high and low parts of. Since we are on the Earth, it looks to us, from. The Earth and its oceans move with respect to each other, because of the. Second, the moon. Earth. That means that the moon is not where it has always been. Earth the Earth moon system clearly must have evolved over time. Can we. figure out how the Earth moon system has evolved I will review the answer to that question in. Tidal Evolution of the Earth Moon System. The description I have given so far is necessarily general, and leaves out a lot of details. But there is a lot of physics and mathematics hidden behind that laymans facade, and it. Earth and the moon. I will not develop any of that mathematics here. I will concentrate instead. Earth moon tidal system. Along the way I will make reference to numerous original sources, books, journal papers and the. Those sources will provide the reader with all of the mathematical andor physical details. Readers eager to know more are encouraged to consult those sources. It was not possible to study tides in any quantitative, physical or mathematical sense, until. Philosophiae. Naturalis Principia Mathematica in 1. Since then a number of eminent scientists have.

Darwin considered ocean tides, and made. Earth. Today we know that ocean tides are much more important than solid body tides. Thomson was. the first to show that tides transferred angular momentum from Earth to the moon, and that. Earth. But Darwin was the first to. Teamviewer 7 Serial Nod32.
