  1. what causes rocket propulsion?

    1. Rocket thrust is caused by pressures acting in the combustion chamber and nozzle. From Newton's third law, equal and opposite pressures act on the exhaust, and this accelerates it to high speeds.

  2. How does Newton's three laws apply to a rocket?

    1. Newton's Third Law states that "every action has an equal and opposite reaction". In a rocket, burning fuel creates a push on the front of the rocket pushing it forward. This creates an equal and opposite push on the exhaust gas backwards.

    1. The Saturn V was a three stage rocket, which performed two staging maneuvers on its way to earth orbit. The discarded stages of the Saturn V were never retrieved. The other type of staging is called parallel staging.

    1. There are two main classes of propulsion systems, liquid rocket engines and solid rocket engines. The V2 used a liquid rocket engine consisting of fuel and oxidizer (propellant) tanks, pumps, a combustion chamber with nozzle, and the associated plumbing.

  5. Hi sir
    How does a rocket move?

    1. Every action has an equal and opposite reaction. So the third law basically says that if you shoot out stuff in one direction you will move in the other direction. This is how rockets work in a vacuum. They have a source of fuel which is heated up so that it expands and is pushed out of the rocket.

    2. Image result for What is the structural system of a rocket?
      In flight, a rocket is subjected to the forces of weight, thrust, and aerodynamics. ... There are four major systems in a full scale rocket; the structural system, the payload system, the guidance system, and the propulsion system. The structural system, or frame, is similar to the fuselage of an airplane.

    1. Rockets are now used for fireworks, weaponry, ejection seats, launch vehicles for artificial satellites, human spaceflight, and space exploration. Chemical rockets are the most common type of high power rocket, typically creating a high speed exhaust by the combustion of fuel with an oxidizer.

    1. Rockets work in much the same way. Exhaust gases coming out of the engine nozzle at high speed push the rocket forward. Most modern launchers, such as Europe's Ariane 5, are very complicated and weigh hundreds of tonnes at liftoff. Most of this weight is fuel, such as liquid hydrogen and liquid oxygen.

    1. Rockets work by a scientific rule called Newton's third law of motion. ... The exhaust pushes the rocket, too. The rocket pushes the exhaust backward. The exhaust makes the rocket move forward.

  14. What is the propulsion in a rocket?

    ReplyDelete
    Replies
    1. In a rocket engine , fuel and a source of oxygen, called an oxidizer, are mixed and exploded in a combustion chamber. The combustion produces hot exhaust which is passed through a nozzle to accelerate the flow and produce thrust. ... There are two main categories of rocket engines; liquid rockets and solid rockets.

    Replies
    1. The result is effectively two or more rockets stacked on top of or attached next to each other. ... By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased.

    Replies
    1. he propulsion of all rockets is explained by the same physical principle: Newton's third law of motion. A rocket's acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket.

  19. what is the point of having a nose cone on a rocket?

    ReplyDelete
    Replies
    1. Nose cone and rocket diameter affect drag. The amount of air resistance that opposes a rocket's motion depends mainly on the shape of the nose cone, the diameter of the rocket and the speed of the rocket.

  20. what is a plasma rocket engine?

    ReplyDelete
    Replies
    1. VASIMR, short for Variable Specific Impulse Magnetoplasma Rocket, uses radio waves to ionize a propellant into a plasma. Then, a magnetic field accelerates the plasma from the rocket engine, generating thrust.
