When it comes to the science of force, there’s one thing that is for sure it’s complicated. In fact, when asked this very question, scientists not only couldn’t agree, they didn’t even have a good way to figure it out. But was until 1687 that Isaac Newton published his Mathematical Principles of Natural Philosophy. Within this text, Newton proposed his theory of universal gravitation, which stated that every object in the universe attracts every other object.
The Moon Pulling on The Earth
This is a theory where everyone and everything pulls on every other thing. However, not everyone moved the same way or with the same amount of force. It didn’t even matter what type of object you were a rock, water, air-whatever it was everybody pulled exactly for themselves regardless of mass or density.
Yes, friends that mean everything in this universe attracts itself to everything else no question about it because there’s only one moon pulling on the Earth.
The Earth Pulling on The Moon
Placing something outside of The Universal Gravitation Theory was a lot trickier than one would think because you couldn’t simply say “oh well people pull in different directions and so we don’t know how much mass an object has, therefore it is impossible to determine which object pulls harder. That’s why scientists were confused.
In reality, all objects with no exceptions are always pulled exactly at 1G. What Newton created You are probably saying to yourself now: “But what about the opposite of universal gravitation? What is the force that keeps everything in order?” OK, I understand. So let’s do some math.
Which Exerts More Force
As the Moon pulls on Earth, the Earth rests in a soft place. A hard place would push (deter) both objects around with equal force, but only when there’s friction between them. However…
If something is infinitely dense it will always be at rest no matter what direction you give it. If we look at matter under this microscope all of our everyday stuff everywhere outside in The Universe doesn’t even exist. The matter is moving and exerts more force.
- The gravity properties of gravity. Gravity is explained as an interaction between objects that have mass. Mass is described as the number of electrons, protons, and neutrons that make up an object. The gravitational interaction is a force with specific properties.
- The gravitational force between two objects. It depends on the mass of both objects involved in the interaction
- The greater the mass of an object, the greater the gravitational force it has. This is due to the fact that gravity is a force of attraction between masses.
- The gravitational force decreases as the distance between the two objects increases.
- The force always points in the direction of the other object and is always in the direction of the other object’s center of mass.
Therefore If a Planet Moon Pulling on The Earth is Stronger Than the Earth Pulling on The Moon
In this way, every force of attraction (or “force”) will be proportional to the object’s mass and inversely proportionate to the distance between each other objects.
Since he had just proven that planets could fall from the sky due to gravity, Newton did a quick calculation of what would happen with objects on Earth where two greater-than-earth masses attracted one another by forces equal but opposite that in nature.
The Moon is Closer to The Earth, Which Makes its Pull Stronger
This means that a planet moon pulling on Earth is pushing the Moon out of orbit and causing it to slowly recede from (and toward) the Earth.
At least, this would appear to be true for objects orbiting in an elliptical orbit around a point mass in space. Of course, there are some problems with Newton’s model, what if these greater-than-earth masses were not heavenly bodies but planets instead? If they did have Moon be closer to the Earth, it which makes its pull stronger.
Gravity is a Result of Mass, and Since The Moon Has Less Mass Than the Earth, its Gravitational Pull is Weaker
Gravity As Newton discovered, the combination of these two anomalies presented some very scientific questions. If an object was orbiting in a more elliptical orbit, closer to its primary mass would have more force pulling and dragging it inward that another body that is far away and at an equal distance from both objects?
And if planets did pull one another by mutually-opposed forces along their equatorial plane –their mutual gravitational interaction– what happens when they are in obit is a result of mass, and since the Moon has less mass than the Earth, its gravitational pull is weaker.
At least, that’s the model for what everyone believes. This just means both bodies are “inertial” – in stable equilibrium– and do not exert force upon one another as Newton thought they did (which can be proven).
There is no known reason why everything needs to orbit around anything else. In fact, if you double an object’s mass once again—by centripetally concentrating it back into a single object—its weight doesn’t double nor does anything else.
The Moon’s Gravity Affects the Earth’s Tides
So far as we know, they don’t (collisions and explosions notwithstanding) with the mass of our Sun. No planetary bodies such as planets are in orbit around these masses , but we can assume that’s because, if the Earth is at a particular distance from the Sun, there would be no point for it to orbit.
Therefore, to form planets orbiting around these mass points, something else needs to gather those masses together or initiate them into orbital motion. There are two very popular explanations as of today. Jovian planet formation and dark energy (not Solar ).
Two Alternatives A) The sun formed from a gigantic cloud of dust and gas, making an intermediate star. In this case, however, the entire structure is simply pulled together by gravity (or perhaps it gets denser when everything is compressed into a small space, I’d rather let someone with knowledge in that field help me out).
The force exerted by the Moon on the Earth is greater than the force exerted by the Earth on the Moon. This happens because the Moon is closer to the Earth. The closer an object is, the greater the force it exerts. Thank you for sharing your thoughts.
