Why Should Those Who Have the Opportunity and Opportunity Choose to Live in the South of the World?

I have written articles about our weight before.

Weight = mass x gravitational acceleration

F = m.g

Newton came up with these formulas in his time and told us that the earth attracts us. Maybe an apple fell on his head and he came to his senses. A light flashed in his head and he found the formulas.

Gravitational acceleration has been calculated as: 9.81 meters per second2

We know that this acceleration varies depending on our altitude. At sea level and at the top of Everest, the traction force of the ground on us is slightly different.

Actually, the place does not attract us, but since the subject of today's article does not include these details, let's say that the place attracts us. Otherwise, the earth bends space-time and we feel the earth pushing us back, which prevents our universal journey towards the center of the earth.

Yes, Newton actually developed the formula that calculates the traction force between two masses, expressed as F=G.m.M/r2.

A constant number referred to here as G is the gravitational constant of 6.67x10^-11 N (m/kg)2.

If we write our own mass instead of "m" in the formula, the mass of the world instead of "M", and the distance from the center of the earth to our center of mass instead of the distance mentioned as "r", that is, if we enter the radius of the earth in short, the force we call "F" will give our weight.

Let's calculate: If we say that the mass of the Earth is 5.972

Do not say that my mass is not 8 kg, I am 80 kilograms, even though both are the same unit, our mass is approximately one tenth of our weight, because as I wrote above, the acceleration of gravity is 9.81 meters / second2. If you put it into the formula, Weight = mass x gravitational acceleration, F=m.g, you need to divide your weight by the gravitational acceleration to find your mass. You can do this by dividing your round calculation weight by 10.

At this point, a question comes to my mind. Okay, even if our mass does not change and our weight changes at sea level or on the top of Everest, would there be a change if we were standing at the pole at sea level or on the equator?

Why did this question come to my mind?

Because the world does not stand still! It also rotates around itself. As we rotate, we also rotate with the world.

When you rotate something, centrifugal force occurs.

Didn't we say in a previous article that in this way, spacecraft in orbit have a zero-gravity environment?

Therefore, it seems to me that the weight of someone at the equator must differ from the weight of the same person at the poles.

After all, if you remember from an article I wrote a while ago, we actually rotate quite fast along the equator with the earth, 1667 km/h.

If we were standing at the pole point, we would only be rotating around ourselves like whirling dervishes, taking one tour in one day.

This situation came to my mind; under normal circumstances, someone who is on the equator will feel lighter.

Of course, in this calculation, I assume that the world is a complete sphere. Normally, the shape of the world is a sphere that is flattened at the poles and bulged at the equator. This shape is called an oblate spheroid.

The decrease in radius resulting from this flatness at the poles also has an increasing effect on our weight; as a result, the distance between the two centers of mass becomes shorter. This will have a slightly increasing effect on the weight in our formula, which is inversely proportional to the square of the distance. But I will ignore this effect.

I'm just curious about the centrifugal effect caused by the rotation of the earth around itself. I wonder how much lighter our weight is due to centrifugal force alone?

I will calculate this.

What is the formula of centrifugal force?

F = m. V2/r

Here, "m" means mass, "V" means rotation speed, and "r" means distance from the center of rotation.

If we convert the unit of our speed, which is 1667 km/hour at the equator, to m/sec, we can say that our speed is 463 meters/sec.

Although this is a magnificent speed under normal conditions, since the distance to the center of the earth is quite long, the result of the calculation is 270 grams for a person weighing 80 kilos.

Well, even this is something for weight loss enthusiasts. I think if you want to feel lighter, go south.

I have written before, we return faster in the south, and living fast is another formula for staying young, you know. Einstein proved this fact with formulas.

And look, you feel lighter. However, in order to calculate the exact value, it is necessary to take into account the angular effects, that is, I made the calculation on the equator, there are angular components of the effect higher up. So the effect is decreasing.

However, even if it is 200 grams, it would probably be beneficial to feel lighter.

By the way, I don't understand why Newton did not include this centrifugal effect in his gravity formula.

However, Newton knew about the centrifugal force. When a horizontally rotating plate or a carousel and an immobile object on it start to move, it will tend to slide outwards. In other words, the object will gain an acceleration from the center outward. Newton said that a force must be acting on this object in the direction of acceleration (outward). He said that this force, which does not actually exist, is called centrifugal force.

So he knew centrifugal force. Since he knows that the world revolves around himself, I think he wrote the formula incompletely.

Although it has a very small effect, in modern formulas these effects are included under the name of angular momentum.

Go south, there are all kinds of benefits. Istanbul is already crowded enough, I think you will feel much lighter and younger in the south.
