What is a Rocket?
Do you know what a rocket is? In order to understand rockets, you need to know a few things. A rocket is an object that flies through the air. It can carry a satellite into orbit, it can carry people for exploration, and it could be used in warfare. Rockets are usually tube shaped and very streamlined. A rocket is a flying object that runs on jet propulsion. (McDonnell Douglas Delta II Rocket lifting off) The McDonnell Douglas Delta II Rocket is the rocket that put the Mars Rover on Mars! According to the Rocket Manual for Amateurs, by Captain Bertrand R. Brinley, jet propulsion is the “force, motion or thrust resulting from the ejection of the propelled matter within the propelled body.” This means that when the fuel is ignited, it starts to take up more room than it did, and it is the change in the size that makes it eject, or propel the rocket. This happens when the fuel ignites for both solid and liquid fueled rockets. Newtons Law of Physics states that for every action, there is a
The word “rocket” may refer to a couple of different objects. A rocket can be a type of flying vehicle used by astronauts, space explorers, and even unmanned space flights. A rocket can also be a weapon, fired by anything from tanks to airplanes. A model rocket is a small toy used by hobbyists to propel fireworks or to practice direct air launching. No matter the type of rocket, there is always a propellant or chemical reaction used to set off the rocket in motion. This propellant can be gasoline or more complex mixes such as liquid oxygen and liquid hydrogen. Sometimes a rocket uses other propulsion systems to get into the air. A rocket is the main propellant of spacecrafts. Without it, it would be impossible for artificial satellites, spacecrafts, and other interplanetary vehicles to reach enough of a thrust to leave Earth, reach space, and then establish a flight pattern. The difference between the rocket used as a weapon and the rocket used in spacecrafts is mainly in the construct
