Tidal forces in the early solar system
I'm reading a book called "Gravity from the ground up" by Bernard Schutz. I don't understand this section from Investigation 13.3 on page 159, which discusses the formation of the solar ...

Is the tidal force at the Roche Limit equivalent to the gravitational force of the body?
There is a pebble on the surface of the earth facing a massive celestial body. If the tidal force becomes equal to 9.81m/s^2, Then it will float.
Would this be at the Roche Limit then?
Does that mean ...

How to calculate equilibrium height of tidal bulge?
I am trying to model the shape of the tidal bulge caused by the moon.
I asked GPT for a formula and it gave me equilibrium tidal bulge height as
$$\frac{2 R_{earth} G M_{moon}}{3 r^3 \Delta g}$$
and ...

What happened to Newton 3rd law if our Moon is moving away at 1.5" yearly? [closed]
Our Moon is going away and I read that it is the culprit is our ocean, but then what happens to Newton 3rd law there should be an equal and opposite forces too so where's that? Is it absorbed by the ...

Will the moon ever proceed to lose its orbit and hit the earth?
Assume that the moon it orbiting the earth in a circular trajectory.
It will experience an acceleration directed towards the centre of the earth given by $\frac{GM}{R^2}$ where $G$ is the universal ...

Why does the Earth move away from the Sun?
From the (Wikipedia's) definition of the astronomical unit $AU$, we have that it is defined as:
$AU=\sqrt[3]{\dfrac{GMD^2}{k^2}}$
Where $k\approx0.01720209895$ is Gauss' gravitational constant, $G$ is ...

On the tidal heating of a moon. What is the second Love number?
Years ago it was asked here how to calculate the tidal heating of a moon orbiting another body with a simple equation. The answer is very detailed. They explain the equation, its shortcomings, the ...

Correct explanation of tides [duplicate]
In the explanation of tides on earth there seem to be different versions for the second water bulge on the side opposite to the moon, while everybody seems to agree that the bulge on the moon side is ...

How does a gas giant planet hold it's spherical shape when it has tidally locked rotation in it's orbit around the Sun?
How does a gas giant planet hold its spherical shape when it has a tidally locked rotation in its orbit around its Sun? Wouldn't it fall apart without its gravitational pull from the rotation? How ...

Possible non-negligible physical effects that relate planetary/lunar geometry and seismic activity such as earthquakes?
Could any forces from the moon, the planets or the sun in orbit hypothetically influence seismic events on earth? And if yes how to approximately calculate and compare the magnitude of the forces?

Is tidal energy an infinite source of energy?
As tidal waves are caused due to gravitational force which acts infinitely until the presence of mass (the Moon) which make me think of an infinite source of energy. So what's wrong in here?

Why is the time difference of equal tide states not 50 minute if one lunar day is 24 hour and 50 minutes?
I do understand that tidal forces are caused by de difference of gravitational force between both opposite points of the earth where a bulge is formed.
I do understand that a lunar day is ruffle 24 ...

If the Earth and the Moon were smaller, would moon tides be more or less intense?
If the Earth and Moon were smaller (and everything on them too, but keeping the same average density and the same "relative" distances, I mean... the same proportions!), would the tides ...

Falling stones attached by a string
Suppose we have two stones, one "big" (A) and one "small" (B), the smaller one over the big one at the moment of free fall. Suppose also that a string of a certain length is ...
