이제는 중력값을 이용해서 물체가 떨어지는 데 걸리는 시간을 구하는 단계에 와버렸기에 중력이란 나에게 더 친숙한 존재이다. 괴팍한 천재 과학자 뉴턴이 떨어지는 사과로부터 만유인력과 중력이란 개념을 생각해낸 이후, 이 중력이란 도구는 지금도 내게 있어 물리라는 과목에 속해 나를 괴롭히는 수단이다. 하지만, 앗 시리즈를 통해서 중력을 재미있게 학습하는 방법을 알게 되었다.
The gravity is well known to you, because you must suffered about gravity when you lived. When you threw a ball into the sky, and the ball just fallen to the ground again. And you must have tried to get our of Earth by jumping high. It just made you breathe hard. So, what is gravity? Why this gravity is catching our ankle?
You should know about the universal gravitation. It says the small bacterias have the universal gravitation to our body. But, we just can't feel this because they are too small. The universal gravitation is inverse properted to the interval. So, if the rocket get out of the earth, than they cannot feel the power of Earth because they are too small.
Many people tried to tide over the disturb of gravity, and I think they finally did this. They shoot many satellites and get informations from them. I hope people will know much things about gravity.
