Rockets must achieve very high speeds to overcome Earth's gravitational pull and reach space. This high velocity, called escape velocity, allows the rocket to break free from the atmosphere and avoid being pulled back to the surface. Additionally, reaching such speeds is necessary to ensure the rocket can successfully enter orbit or travel to other celestial bodies. The high speed is achieved through powerful engines that burn fuel at a rapid rate, generating the thrust needed for ascent.

When did the first rocket take off?
The term 'rocket' is very General, the first recorded flying object to take off using rocket propulsion was either the Me-163 or the V-1 Doodlebug, both made in Nazi Germany.
What is the highest speed ever reached by a rocket?
That question is not very specific. The answer in general is the speed of light. A better question would be to specify what object or thing in respect to what, like what was the fastest speed ever achieved by a manned land vehicle.
What keeps a rocket from falling back to the surface or moving off into space?
A rocket is propelled by its engines to overcome Earth's gravity and achieve enough speed to enter orbit or reach its destination. In space, there is no air resistance or opposing forces to slow it down, allowing it to continue moving forward. To prevent a rocket from falling back to Earth, it must reach a minimum speed known as escape velocity.
How do rockets propel it self?
Rockets propel themselves by expelling gas or liquid at very high speeds out of a nozzle at the back of the rocket. This action creates an equal and opposite reaction force that pushes the rocket forward. This principle is based on Newton's Third Law of Motion.
How long does it take to get to space from earth?
Not very long at all; Apollo 11, for instance, entered orbit about 12 minutes after takeoff.A few minutes, in a rocket. "Space" is normally defined as an altitude of about 100 km. or so - at that altitude, the Earth's atmosphere becomes insignificant.
Rocket works on the principle of conservation of?
linear momentum. A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.
The earth's gravity pulls all things towards the earthaircrafts cannot fly beyond a certain limit due to gravityhow did scientist solve this problem to send avehicle out into space?

Did the rocket nell fail?
No, it worked as designed. While it didn't fly very high it did take off and fly as far as the propellant would carry it. This was the first successful flight of a liquid-fueled rocket.
Working principle of rocket engine?
A rocket engine, or simply "rocket," is a jet engine[1] that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.Rocket engines as a group, have the highest exhaust velocities, are by far the lightest, and are the most energy efficient (at least at very high speed) of all types of jet engines. However, for the thrust they give, due to the high exhaust velocity and relatively low specific energy of rocket propellant, they consume propellant very rapidly.
What is the difference between model rockets and real rockets?
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
How speed of the repulsion motor can be reversed?
it has very high speed but no load
How long does it take to travel 39.20 miles at 65 mpr?
Very very long because it would take me years to discover what speed 65 mpr represented!Very very long because it would take me years to discover what speed 65 mpr represented!Very very long because it would take me years to discover what speed 65 mpr represented!Very very long because it would take me years to discover what speed 65 mpr represented!
What would happen to the speed of sound at a very high altitude?
The speed of sound increases with altitude due to the decrease in air density. This means that at very high altitudes, where air density is lower, the speed of sound will be faster compared to at sea level.
Why does a molecule of a gas move at high speed?
If the force of the engines is constant, then the rocket's acceleration could increase as time goes on because its mass is decreasing ... it's losing the mass of all that fuel that's burning to keep the engines running.
Why no load-speed of a dc series motor is very high?
high torque
How long would it take to get to uranus from earth using a rocket?
It would take approximately 6-7 years to travel from Earth to Uranus using current space travel technology. The exact duration would depend on factors such as the speed of the rocket and the alignment of the planets.
How dangerous is a tire blow out?
It can be very dangerous especially at high speed. Many accidents happen due to this very thing. Blow a tire at high speed and you may very well loose control of the vehicle.
