Physics Behind Why Rockets Fly

In order for a rocket to fly, some basic physical rules must be followed. It can not escape from the basic rule that the center of gravity must be before the pressure center. The center of gravity center of gravity or Cg is expressed as if all masses are concentrated on that point. Simply put, you can balance rockets with your fingers. Cg is also the point where the rocket rotates. This is very important for the stability of the rocket, you will see it soon.

"I tend to handle things from a physical framework," Musk said in an interview. "Physics teaches you from the first principle, not analogy, so let's look at the first principle: What is a rocket? In addition to aerospace grade aluminum alloys, some Titanium, Copper and Carbon Fiber. Then I am Q. What is the value of these materials in the Commodity Market? We can see that the material cost of rockets is about 2% of regular price theoretically, In principle, we need to deeply deeply understand the basics of the situation deeply: René Descartes, a French philosopher and scientist, now adopts a method called Descartes skepticism to accept this method Everything is suspected until I leave a purely doubtless truth he sees. "

Fiorello Bodini woke up at night and went out to listen to rockets flying to Martian, Saturn, and Venus rockets. He is a crap dealer, but his family succeeded in saving enough money to get on the rocket. The acquaintance tells him that he is going to fail, the rest of his family is indignant no matter where he goes. His children are excited about this possibility

The rocket consists of thousands of complicated and complex parts. Rockets need to concentrate so that the whole team fly properly for each subsystem. And usually it will not work. In the past few weeks there was a pre-flight checklist, which took many years to assemble individual rockets. Given the inherent complexity of rocket launch, the 95.43% US launch rate is strange. Excellent scientists and engineers manufacturing rockets are most cautious and must understand the most intimate details of these huge machines.
