What is the relationship between thrust and pressure?
thrust and pressure are dirrectly proportional 2 each other frm d formula pressure =perpendicular force /area
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
How does an aeroplane create lift?
In an aircraft, the powerplant provides thrust. And this thrust, combined with the lift provided by the wing's design, air has to move more quickly over the top of the wing (AIRFOIL) than the air underneath the wing. Faster moving air has less pressure than slower moving air, Bernelle's Principal, so suction on the upper skin of the airfoil when it moves through the air (by thrust), creates lift.
Do shuttle astronauts cease to hear engine thrust sounds once the shuttle and rockets exceed the speed of sound?
yes
What are some similarities between a thrust stage and an arena stage?
An arena stage is a theater stage surrounded or nearly surrounded by the audience and a thrust stage is a a stage that projects beyond the proscenium so that the audience sits around the projection.One side of the arena stage does not have the audience and on the trust stage every side of it is covered.
What does the thrust push against in a jet engine?
The thrust in a jet engine pushes against the surrounding air. As the engine expels high-velocity exhaust gases backward, the equal and opposite reaction propels the aircraft forward.
How to Thrust then grind?
First stab then crush. To thrust is to penetrate fully, when that has been achieved the grind is when you as the male, gently grind your pubic bone against that of your partner [female].
Why does a shuttle need thrust?
To lift off the earth against the force of gravity. To go up.
Can a propeller work in space?
No, a propeller requires a medium, such as air or water, to push against in order to generate thrust. In the vacuum of space, there is no medium for the propeller to work against, so it would not be able to generate thrust or propel a spacecraft.
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.
What is the name of the force that pushes agisnt an aireplane as it tries to move forward through the aire?
'Thrust' pushes against it from the rear, and 'drag' pushes against it from the front.
What is the force that is created by a rocket called?
The force created by a rocket is called thrust. Thrust is generated by the expulsion of gas at high speed from the rocket's engines, following Newton's third law of motion: for every action, there is an equal and opposite reaction. This thrust propels the rocket upward against the force of gravity.
Is thrust the upward force the opposes the force of gravity?
Actually thrust is aerodynamically involved, its the driving force that accelerates the aircrafts in forward direction and the opposite force is drag. The opposing force against gravity in a flight is lift.
What is thrust capacity?
Thrust Capacity is how much thrust it can take :D
What two forces of flight oppose each other?
Drag and thrust oppose each other in flight. Thrust is the force that propels an aircraft forward, while drag is the force that acts against the motion of the aircraft, slowing it down.
Which airway technique will prevent movement of the head spinal cord and neck.?
Jaw-Thrust Technique
What is the past tense and past participle of thrust?
Thrusted is the past tense and past participle of thrust.
