What is gravity?

• Writing on the occasion of Gravity Day.

Before Newton said, nobody knew about the attraction.  But because of this we are living on earth. Gaita Mahabibek and the planet - from the siege of the stars and the Chad - to falling into one-on-one troubles, gravity is shaking even after playing football.  And one day of the year it may have been something like that. Asef Rahman, I am sharing some interesting information on the mysterious fascination on Gravity Day.

Speed and Weight :

Weight gains with speed and space, even though one is always there.  And this is gravity. Because of The earth's gravity is down to it. Constantly pulling.  The soil, on the other hand, holds Tema. Have kept Because of the hold on the ground, you gain weight.  But when the railer. Continue down the coaster. Then become weightless. Because that's the time. No one holds Tema from gravity.  Again, when the novice rockets back to the seat. As she goes upstairs, hers. It seems that his weight has increased a few times. Because at that time he wanted to rise as fast as he could, pushing him in the seat. 

The body will not grow:

  Gravity has occurred on the earth from inside the ball.  Evolution of life. So when growing up in an environment without gravity, most animals are in contact with the earth.  Can't eat Weight of our body. In the bones that work, they become. Okay. Increases the amount of calcium in the body.  No The back and legs of our body. Strength did not build on the muscles that work in the house. That is, because of gravity, we have grown in this form today.  Without attraction, people would become reptiles.

Tunnel between the earth.

  Do not think that the earth is dirty - you have to dig a hole in it.  If anyone jumps into that hole. What will happen then? We know, to read.  The speed of the object at the corners keeps increasing. It is gravitational acceleration.  It was a fall this fall. Individual speed is up to about eight kilometers per second. will be !  But at the same time, the weight will decrease. That means it will seem to the person, his weight is in order.  Is decreasing If you go to the bottom of the abdomen at one point, the weight will fall to zero. Of course, the person will not hang there.  Due to the high speed will continue to fall through the tunnel. But this time, it is the turn of the pace. At one point in her reading, she would feel like she was going upstairs.  Then when he. The opposite side of the tunnel will rise, so if no one catches him, he falls again. Will go But this time he is not on the opposite side - he can get up. Because there is wind inside the tunnel.  The person who is pushing with the wind will slow down and he will float in the stomach of the earth.

Fish head:

Where is the relationship of gravity with fish head?There is . Fish have no hands and feet.  It can also rotate in a weightless environment. And therefore it is not possible for the fish to swim, which side is above the water, and the other.  Below. Luckily, except for two species, all the fish have a shredded stone. The stone called calcium carbonate is called autolith. The fish can sense where the stone is falling.  And that is how he understands the pull of gravity.

One person at a place:

The world is not a galleon at all.  So gravity ball is different on each side of it.  NASA sent two satellite satellites called Grace to find out where the attraction was.  It is seen that gravitational force is the most active in the Arctic region of the earth.  Peru on the other hand. The highest attraction force at Mount Nevado Hills.

The speed of gravity:

 The earth revolves around the sun due to gravity.  But the sun was vanished after being caught? Will the world find it right away?  According to Newton, gravity is something that is immediately available. Einstein, on the other hand, says.  Gone, gravity hack and whatever - e hake, Alare. Nothing could be more dynamic than (in seconds. Three million kilometers).  Of gravity as that. The speed is equal to the speed of the ala. That is, the sun is shining. If we disappear, we will find it eight minutes later!  Then the world will continue to revolve. The gravitational wave, which collided with a pair of neutron stars around the 20th. Scientists were able to observe that the gravity wave was created.  At the same time, they are the path of the ala that is scattered in the satellite. See. It is seen that the velocity of the gravitational wave is not only slower than that of Ala, but also somewhat higher.

Gravity swirls:

If you use a rocket all the time to send navigation to the far corners of the planet, you will see that Mars is out of fuel.  Even with the desire to go straight to the rocket, Chad has the most to think about. Gravity has now escaped this thought. Power.  Remember, a heavy object binds to a rope. You are surrounded While walking around, someone cut the rope in a tactic. What will happen  It can be seen that the object has slipped away. Gravity is that. The rope will work. The novel is the attraction of the world. Whenever he moves around in the ball, he hoots himself.  Turn the rocket on (means cut the rope), then. As can be seen, there will be a lot more momentum.
