What is the effect of the gravitational pull on a spacecraft object about the mass of a celestial

1.is decelerating into the Earth's orbit because the formula for gravitational potential energy shows that the closer you are to the center, the smaller the potential energy of the celestial body, the smaller the orbital velocity. Therefore, when the object enters orbit, it must be larger than the orbital speed of the Earth, and it will decelerate.

Imagine a spacecraft orbiting the earth, if its speed does not meet the orbiting requirements, it will be pulled to the ground by gravity, this is the reason, first slow down, be pulled to the orbit by gravity and then accelerate in a certain direction, in order to correct the direction of speed, become an orbital flying object.

2.The formula is.

Central Celestial Mass * Mass of the object.

Gravitational force = g*

The square of the distance from the object to the center of gravity of the central celestial body.

So you can see that g is a constant.

The mass of the earth is about 60 trillion tons.

Let's calculate the gravitational range.

3.It is clear from the above that if it is the same object, the heavier the celestial body, the greater the gravitational force.

4.Entering the lunar orbit is to enter the earth's orbit first, after changing the orbit to approach the moon (not in the same orbit as the moon), although the height is close, but it is not necessarily synchronized with the moon, right, if you enter the moon's orbit around the earth, the result is useless to chase in the same orbit with the moon, after all, it is the same orbital speed, and you can't catch up. So orbit in a lower or higher orbit first, because the period is not the same, and when it turns closer to the moon, then change the orbit into the lunar orbit!

Mom, I'm tired of it

1.It should be accelerated into gravitational orbit, and after entering orbit, the spacecraft will operate with very little power, of course, slow down!

2.Gravitational attraction between everything, but because.

f=g*m1*m2 r 2, so the relation to distance is that the distance is larger, the gravitational force is smaller but there is always! It's pretty standard.

So, it's related to m!

。。！I really don't understand, I sigh with admiration...

I'll wait for everyone's answers, and I won't either.

Summary. Yes, the greater the mass, the greater the gravitational pull. Because matter causes space-time to bend, the degree of curvature of space-time determines the magnitude of gravity.

When the matter (to be precise, the density of matter) is larger, its energy momentum tensor is larger, according to Einstein's gravitational field equation, its Richie tensor is larger (Einstein tensor to be precise), the Richie tensor is composed of gauges, the larger the gauge, the greater the curvature of space-time, so the greater the gravitational force.

Yes, the greater the mass, the greater the gravitational pull. Because matter causes space-time to bend, the degree of curvature of space-time determines the magnitude of gravity. The larger the Richie tensor (Einstein tensor to be precise), the larger the Richie tensor (Einstein tensor, to be precise), the larger the gauge, the greater the space-time bend, so the gravitational force is greater.

Any matter in nature has both inertial and gravitational mass. The term "matter" here is a general term for macroscopic objects and electromagnetic fields in nature, celestial bodies and galaxies, and elementary particles in the microscopic world.

But the space station has mass in space, why can't it generate gravity on its own?

It has a gravitational force, but the distance between two objects is relatively far, so the gravitational force is relatively small.

But aren't people inside the space station?

That's right, the clothes that people wear in the space station are specially made and will be converted to gravity.

This is also convenient for easy movement.

But gravity is real and cannot be eliminated, but can only be counteracted by other forces.

I'm talking about not being able to cancel out the gravitational pull of the space station without any force, is there no more?

No, the gravitational pull of the space station is always there.

Even if it is not affected by other forces, the gravitational pull does not disappear.

Are you talking about other gravitational forces?

Yes, there is mutual gravitational attraction between objects and objects.

For example, there is a mutual gravitational attraction between people and the space station.

Summary. Artificial satellites also have mass, so they also generate gravity. However, because the orbital altitude of the artificial satellite is relatively low and the distance from the Earth is relatively close, its gravitational pull is relatively small.

Moreover, artificial satellites usually move around the Earth at a certain speed, and this state of motion is called "uniform circular motion", in which they are subjected to a centripetal force and therefore do not fall to the Earth's surface.

Artificial satellites also have mass, why is there no gravitational pull? And celestial bodies in space have mass and gravitational pull.

Artificial satellites also have mass, so they also generate gravity. However, because the altitude of the Xinmin orbit of the slippery branch where the satellite is located is relatively low and the distance from the earth is relatively close, its gravitational pull is relatively small. Moreover, artificial satellites usually move around the Earth at a certain speed, and this state of motion is called "uniform circular motion", in which they are subjected to a centripetal force and therefore do not fall to the Earth's surface.

Celestial bodies in space also have mass, so they also have a gravitational pull between them. When the celestial bodies are close enough to each other, the gravitational pull becomes significant, affecting their motion. For example, in the solar system, there is a gravitational interaction between planets and stars, and this gravitational force determines the co-bonding of their orbits, velocities, and other parameters.

In short, whether it is an artificial satellite or a celestial body, there will be a gravitational attraction in the universe, but due to the difference in the distance and mass between objects, the gravitational force and the harmony effect are also different.

Outside of this height, artificial satellites usually move at a very high speed relative to the Earth and other celestial bodies, which makes them in a state of self-amusement, i.e., the centripetal acceleration is equal to the gravitational force, so it appears that there is no gravitational effect. But in reality, it is still subject to the gravitational pull of the Earth and other celestial bodies.

So, how is it that the artificial satellite itself has no gravity?

The artificial star also produces a gravitational force, but due to its relatively small mass, the gravitational force produced is very weak and negligible. In addition, artificial space satellites usually operate in space along a predetermined orbit, which means that their distance and speed from the Earth are carefully calculated and designed to ensure that they can orbit according to their predetermined orbits and do not cause unnecessary interference to the Earth or other celestial bodies.

Is it the Sputnik itself?

It is also important to note that the gravitational pull of artificial satellites is usually weak and does not have a significant effect on other celestial bodies. But in some special sale tremor situations, such as when two artificial satellites are in close proximity, the gravitational pull between them may become more pronounced and may cause their orbits to change and fail.

Explanation of the theory of relativity.

In fact, gravity does not exist. Or that gravity is just an explanation for this phenomenon. It is different from other forces.

The gravitational force is actually a manifestation of the distortion of space-time, to give a two-dimensional example: a net of straight rubber bands.

1.Put two balls of different masses and the same volume, and the net twists.

2.On the basis of 1, let a ball make a uniform linear motion on the rubber band net, the closer the distance between the straight line and the (same) ball, the larger the trajectory bend.

3.On the basis of 2, let a ball move in a uniform straight line on the rubber band net to approach two balls of unequal mass, the distance between the straight line and the two balls is the same, and the ball with large mass passes through the trajectory bend area.

The phenomena illustrated by 2 and 3 are similar to gravity, and there are also cases where the mass and distance are larger, and the gravitational force is greater.

The object moves in a straight line due to inertia, but moves between the distorted empty states, which is manifested by gravity.

In fact, gravity distorts four-dimensional space-time.

Another example: light distorts when it passes through massive objects, but gravity cannot act on light, so the explanation is that light travels in a straight line and moves in distorted space-time. But the light still travels in a straight line.

The gravitational pull of the celestial bodies themselves can also propel themselves, because they have a strong dynamic force in themselves.

Doesn't push ourselves, just like we ourselves can push others. Let yourself push yourself, this is nonsense, it is simply something that cannot be done.

The gravitational pull of the celestial bodies will propel their own movements, because there is such a function in the design process.

Look at the law of gravitation.

f=gmm/r2

For the Earth and the spaceship, f is the gravitational force between them; r is the distance between the Earth and the spaceship; g is the gravitational constant; m is the mass of the earth; m is the mass of the spaceship.

For the Earth and the spacecraft, the mass of the Earth is constant, and the gravitational constant is of course unchanged. The gravitational force between the Earth and the spacecraft is only related to the mass of the spacecraft and the distance between it and the Earth. The relationship is:

The gravitational pull of the Earth on the spacecraft is proportional to the mass of the spacecraft; It is inversely proportional to the square of the distance between the Earth and the spacecraft.
