Welcome, friends, families, and people of the world! Welcome to the blog of rockets. As you see, today you are going to learn about a slice of information about rockets. To be precise, the history of rockets. Let's begin.
Rockets for centuries were first used for warfare made by the ancient Chinese used as a "fire arrow" to kill of Mongolians in an assault in 1232 A.D. Here's a picture of the first "War rocket" made above.
As time past, as people embedded their names in history, as rockets evolved, the once weapon of warfare which we surpassed already is now an inspiration to explore the corners of the universe. In case you don't know what the modernized rocket looks like, which I'm sure you do, there is a picture of a modernized rocket launching anything. Up, up, and away!.....
Interesting fact:
It was April 12th in 1977 that the first rocket, named Columbia was launched into space. It was a successful mission.
As for kids like me, please don't play with rockets. Here are some things to do with rocket with your parent's permission to keep you busy. A water rocket. The water rocket has the same concept of a real rocket, but only with air pressure and water. Don't underestimate it! A water rocket can actually fly up 90 metres in the air! When it falls down, if successful, the parachute will open up like a real rocket and land safely. What a blast off! (For more information on water rockets click on this link)
A concept, the most important concept is Newton's three laws of motion. Without this concept, a rocket may not fly. Thank you, Newton!
The first law of motion is that if an object at rest will remain at rest and an object in motion will remain in motion at constant velocity unless acted upon by an unbalanced force.
The second law of motion is Force = M x A (Force times Mass)
The last law of motion is: For everty action there is an equal and a opposite reaction.
It applies to rockets because we have to calculate the math before the launch of the rocket or else you can kill people. Without this calculation, a rocket would never fly. (I guess rocket scientists are dangerous.)
