A rocket will move upward as long as the thrust is greater than the force of gravity?
Actually for some time even after the thrust is no longer greater than gravity. When the rocket's thrust is greater than gravity, it will be accelerating (its velocity upwards will increase). When the rocket's thrust is no longer greater than gravity, at that moment it will still have an upward velocity, so it will still travel upwards - it will only travel more and more slowly upwards as gravity starts to sap the rocket's upward velocity towards zero. Once its velocity reaches zero, if gravity is still winning over the rocket's thrust (if any), then it will start to fall back towards the ground.We are assuming a simplistic model (no air resistance, no super-unlucky collisions with meteors, etc.), but this is the basic idea.
What does the engine do on a space rocket?
Provide thrust ... which changes velocity.
The thrust of any rocket engine depends on two factors what are they?
The thrust of a rocket engine depends on the mass flow rate of the propellant and the exhaust velocity of the gases expelled. The mass flow rate is the amount of propellant being burned and expelled per unit time, while the exhaust velocity is how fast the gases leave the engine. Together, these factors determine the overall thrust produced by the engine according to Newton's third law of motion.
What is rocket thrust chamber?
A rocket thrust chamber is a critical component of a rocket engine where the combustion of propellants occurs, producing high-pressure and high-temperature gases. This chamber is designed to efficiently mix fuel and oxidizer, facilitate combustion, and direct the resulting exhaust gases through a nozzle to generate thrust. The design and materials of the thrust chamber must withstand extreme temperatures and pressures while maintaining structural integrity. Overall, it plays a central role in determining the performance and efficiency of the rocket engine.
What is the temperature inside the rocket thrust chamber?
more then 190 degrees.that is hot.
How many pounds of thrust did the rocket achieve on liftoff?
The thrust of a rocket on liftoff can vary depending on the rocket's design and size. For example, the Falcon 9 rocket produces about 1.7 million pounds of thrust at liftoff.
How much thrust did a rocket have?
The amount of thrust a rocket has depends on its design, type, and size. For example, the Saturn V rocket used in the Apollo missions had a maximum thrust of about 7.5 million pounds-force (33.4 meganewtons). Different rockets can have thrust ranging from a few thousand pounds-force to tens of millions of pounds-force.
What is the main factor in determining the amount of thrust a rocket requires to leave the earths atmosphere?
The main factor in determining the amount of thrust a rocket requires to leave the Earth's atmosphere is the mass of the rocket. The heavier the rocket, the more thrust is needed to overcome Earth's gravity and propel it into space.
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 the main factor in determining the amount of thrust a rocket requires to leave the Earth's atmosphere?
Payload weight.
How does the size of the Plenum affect the amount of thrust in a rocket?
Balls in ya mouth
What is the total amount of thrust produced by the rocket that took the man to the moon?
33445590
How many pounds of thrust does a A8-3 model rocket give?
The A8-3 model rocket engine produces approximately 2.4 pounds of thrust at liftoff. This thrust is generated for a duration of about 3 seconds, allowing the rocket to ascend rapidly before the ejection charge deploys the recovery system.
What is the factor in determining the amount of thrust a rocket requires to leave the earths atmosphere?
Payload weight
How does a rocket function?
A rocket functions by burning an internal fuel source as a propellant. The thrust is then pushed through a nozzle to increase performance.
How many pounds of thrust does the first stage of the Apollo rocket have?
The first stage of the Apollo rocket had about 7.5 million pounds of thrust, generated by five F-1 engines. This massive amount of thrust was needed to launch the rocket and overcome Earth's gravity.
How do rocket thrusters work?
Rocket thrusters work by expelling a high-pressure gas out of a nozzle at the back of the rocket. This action produces a reaction force in the opposite direction as per Newton's third law of motion, propelling the rocket forward. The amount and speed of gas expelled determine the thrust generated by the thruster.
