Rocket ships are capable of reaching incredible speeds and making the journey to space a far quicker, more efficient process. But just how fast do rocket ships go? In this article, we’ll explore the speeds of various types of rocket ships and learn about the forces behind these incredible machines.
The History of Rocketry
The history of rocketry dates back centuries, with the first recorded use of a rocket-like device taking place in 1232 during the Siege of Kai-Fung-Foo in China. The invention of gunpowder led to the development of rockets that could be fired from a cannon or a makeshift rocket launcher.
By the late 19th century, rockets had been developed for use in military technology, but the development of rocketry as a means of space travel was still decades away. It wasn’t until the early 20th century that the technology and science of rocketry began to be studied by scientists like Robert Goddard, Konstantin Tsiolkovsky, and Hermann Oberth.
The Physics of Rocket Propulsion
The science of rocket propulsion is based on Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction. In other words, when a rocket is propelled forward, exhaust is expelled in the opposite direction. This exhaust is generated by the burning of fuel, usually liquid oxygen and kerosene, which is ignited by an igniter. This process is known as combustion.
The combustion of fuel creates a high-pressure exhaust that escapes from the rocket through a nozzle. This exhaust is expelled at a high velocity and pushes the rocket in the opposite direction, propelling it forward. The greater the pressure of the exhaust, the greater the force that is exerted on the rocket and the greater the resulting velocity.
How Fast do Rocket Ships Go?
The speed of a rocket ship is determined by several factors, including the power of the engine, the design of the rocket, and the amount of fuel used. Generally speaking, most rocket ships are capable of reaching speeds of up to 8 kilometers per second, or 28,800 kilometers per hour.
The speed of a rocket ship can also be increased by using multiple stages. A two-stage rocket, for example, uses two separate engines, each with its own fuel supply. By burning fuel in two separate stages, the rocket can accelerate more quickly and reach higher speeds.
The Fastest Rocket Ships
The fastest rocket ships ever built are the Saturn V rockets that were used in the Apollo 11 mission. These rockets were designed to reach speeds of up to 11 kilometers per second, or 39,600 kilometers per hour. The Saturn V was powered by five F-1 engines that burned a mixture of liquid oxygen and kerosene.
The second fastest rocket ships are the Falcon Heavy rockets that are used by SpaceX. These rockets are capable of reaching speeds of up to 10 kilometers per second, or 36,000 kilometers per hour. The Falcon Heavy is powered by 27 Merlin engines that burn a mixture of liquid oxygen and kerosene.
Rocket Ships vs. Traditional Aircraft
The speed of a rocket ship is significantly greater than the speed of a traditional aircraft. A commercial airliner, for example, typically reaches a maximum speed of 900 kilometers per hour. This is less than a third of the speed of the Saturn V rocket, which could reach speeds of up to 11 kilometers per second.
The difference in speed is due to the fact that a rocket ship is propelled by an engine that is capable of generating significantly higher levels of thrust than a traditional aircraft engine. As a result, a rocket ship is able to accelerate faster and reach much higher speeds than an aircraft.
