What are two ways to increase the amount of thrust a rocket produces?

If the mass flow rate through the rocketâ??s engine is increased, then the thrust will be higher. Another way to increase the thrust amount is to increase the exit or initial velocity during takeoff.

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.
What is the temperature inside the rocket thrust chamber?
more then 190 degrees.that is hot.
How many forces acting are on a water rocket?
There are two forces acting on a water rocket. The thrust which the force that is given to the water rocket to make it move, and the other one is the gravity.
How much thrust does a rocket need to take off?
i would suppose that it's because the incline is greatest then..but i suppose rocket means "something unmanned lol". the idea i have in my head says something along the lines of, the object has a path of of travel and when its moving it has a projected path of travel. so if the propellant was to be cut off when the rocket is traveling 100mph, it's not just going to stop..it has energy yet to be released. also i believe that things weigh more the faster they are going, according to Einsteins theory of relativity. but when things aren't moving they don't have a projected path of travel that is anywhere else other than where it is, then. so probably because motion must be established, and once it is, the forward motion of the object aids the propellant, if you will..or is less resistance for the propellant.
How much thrust did a rocket have?
Varies depending on the rocket. The tallest, heaviest and most powerful rocket ever manufactured, the Saturn V, produces 7.5 million pounds of thrust.
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 total amount of thrust produced by the rocket that took the man to the moon?

How does the size of the Plenum affect the amount of thrust in a rocket?
Balls in ya mouth
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.
Rockets move forward because?
because a rocket makes an explosion that is stopped at one end and so can only go the other way. one of the laws of physics is every action has an equal and opposite reaction which, in this case, moves the rocket.One word: thrust, when gas is propelled out the back of the rocket it provides the amount of thrust needed to propel the rocket forward.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
thrust of the rocket engine
Is a jet a kind of rocket?
Jet engines and rockets are different means of propulsion. A jet engine takes in air, compresses it and mixes it with vaporized fuel. The air fuel mixture is ignited and produces thrust out the rear of the engine. A rocket uses fuel wich is burned and produces thrust with no air intake. Rocket fuels can be solid, liquid or compressed gas.
What is the factor in determining the amount of thrust a rocket requires to leave the earths atmosphere?
Payload weight
How could a toy rocket accelerate after takeoff?
As long as the thrust is more than the weight of the rocket (toy or otherwise) the rocket will accelerate. When the thrust matches the weight, the rocket will cruise. When the thrust is less then the rocket will slow.
Center of gravity on a rocket?
It is the point on the rocket where it balances it self, with the pull of gravity, and the amount of thrust it applies back on the ground to move up.
What is the main factor in determining the amount of thrust a rocket requires to leave the Earth's atmosphere?
Payload weight.
