How does a rocket move and change direction in space?
HomeScienceScience IForce and Laws Of MotionTopApplications of Law of Conservation of MomentumWhen a bullet is fired from a gun, the gases produced in the barrel exerts a tremendous force on the bullet (action force). As a result, the bullet moves forward with a great velocity called the muzzle velocity. The bullet at the same time exerts an equal force on the gun in the opposite direction (reaction force). Due to this the gun moves backwards. This backward motion of the gun is called the recoil of the gun. The velocity with which the gun moves backwards is called the recoil velocity.Recoil of GunLet 'M' be the mass of the gun and m that of the bullet. Before firing both are at rest. After firing let 'V' be the velocity of the gun and 'v' that of the bullet. By law of conservation of linear momentum,initial momentum of gun and bullet = final momentum of gun and bullet.The initial momentum of the gun and the bullet is equal to zero since they are initially at rest.Final momentum after firing = MV + mv = 0[The negative sign indicates that the gun is recoiling]Sub TopicsRocket PropulsionNumericals01.Solution:02.Solution:Rocket PropulsionBack to Top The motion of a rocket is an application of Newton's third law of motion and law of conservation of linear momentum.A rocket is a projectile that carries the rocket fuel and the oxidiser, which supplies the oxygen needed for combustion. Liquid hydrogen, liquid paraffin etc., are used as rocket fuels and hydrogen peroxide, liquid oxygen etc., are used as oxidisers. The fuel-oxidiser combination in a rocket is called the propellant.The simplest form of a rocket consists of a combustion chamber in which a solid or liquid propellant is burnt. There is a nozzle at its tail through which the gaseous products of combustion can escape. The rocket forces a jet of hot gases downwards through the nozzle. This is the action. The jet of gases exerts an equal force on the rocket, pushing it forward. This is the reaction. This force gives the rocket a forward acceleration.Rocket PropulsionThe operation of a rocket illustrates the conservation of momentum. Just before launching, the momentum of the rocket is zero. When the rocket is fired, it forces a jet of hot gases with a high velocity through the nozzle. The jet of gases acquires a momentum downwards. Hence, the rocket acquires a momentum of equal magnitude in opposite direction. Thus the rocket moves upwards.With a single stage rocket it is not possible to attain very high speed and hence multistage rockets are designed. In multistage rockets when the fuel of the first stage gets exhausted, the rocket casing is detached and dropped off and the second stage is ignited.
What is a rocket with 2 or more stages is called?
It is called a multistage rocket.
How fast does rocket fuel leave the rocket?
This depends on the fuels used (Liquid Oxygen, Hydrazine, etc) the design contours of the nozzles (if we are talking about liquid fuel rocket engines, and pressure pumps, turbo-chargers etc in the rocket body. The velocity of the rocket is dependent on a good many factors including the chemical reactions of the fuels themselves, the specific impulse as it is called, and as with autos, transmission losses due to plumbing and pipes.
How do you fly to the moon?
New Answer (Clearer)Depends what you mean by "rockets". The term "rocket" can be applied to fireworks, missiles, engines and space craft.If you mean a space shuttle, then, yes, they can carry people.People who go into space in space shuttles are celled astronauts.Previous Answer (Vague)Yes.
Why is George stephenson's Rocket called the Rocket?
because of it's speed.
As the rocket is moving through the Earths atmosphere another force acts against the thrust from the shuttles engines. What is this force called?
Reaction force that is equal and opposite to thrust force from the rocket's engine.
How does a rocket change its speed in space with no air?
Some people (who have not studied physics) believe that rockets work because the rocket exhaust pushes against the air, and therefore in the vacuum of space where there is no air, rockets won't work - but that is not the case. Rocket exhaust doesn't need to have air to push against. The expanding gases in the rocket's exhaust nozzle push against the rocket. The gas has its own mass and its own inertia, and the change in momentum of the exhaust gas causes an opposite change in momentum of the rocket. This can be difficult to grasp because we think of gas as being virtually weightless, but a large rocket can emit literally tons of exhaust. The fact that it is in the form of a gas doesn't change the result; mass is mass, whether solid, liquid, or gas.This is WRONG, rocket DOES work in space.From NASA"A rocket is a type of engine that pushes itself forward or upward by producing thrust. Unlike a jet engine, which draws in outside air, a rocket engine uses only the substances carried within it. As a result, a rocket can operate in outer space, where there is almost no air."How it accelerate"Rocket engines generate thrust by putting a gas under pressure. The pressure forces the gas out the end of the rocket. The gas escaping the rocket is called exhaust. As it escapes, the exhaust produces thrust according to the laws of motion developed by the English scientist Isaac Newton. Newton's third law of motion states that for every action, there is an equal and opposite reaction. Thus, as the rocket pushes the exhaust backward, the exhaust pushes the rocket forward.The amount of thrust produced by a rocket depends on the momentum of the exhaust -- that is, its total amount of motion. The exhaust's momentum equals its mass (amount of matter) multiplied by the speed at which it exits the rocket. The more momentum the exhaust has, the more thrust the rocket produces. Engineers can therefore increase a rocket's thrust by increasing the mass of exhaust it produces. Alternately, they can increase the thrust by increasing the speed at which the exhaust leaves the rocket."http://www.nasa.gov/worldbook/index.html
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.
What is it called when momentum can be transferred but the total momentum does not change?
conservation of momentum
What is the force that accelerates a rocket called?
The combustion of rocket fuel ejects a mass of material at high velocity. In accordance with Newton's third law, the momentum of the ejecta generates an equal and opposite reaction - which propels the rocket forward.
When objects collide the total initial momentum equals the total final momentum is called what?
this is called law of conservation of momentum
What is the product of mass multiplied by velocity?
That is called "momentum".
The product of an object's mass and velocity?
The product of an object's mass and velocity is called it's momentum. It is mostly called it's linear momentum to differentiate from the term angular momentum.
The product of an object mass and velocity is called its What?
That's the object's linear momentum.
