Ion thrusters, which are used by rockets and spacecrafts, use inert gasses to propel them upwards. Most thrusters use xenon gas, but other gases are sometimes used as well, including krypton and argon.

How do thrust drag and gravity affect a hydro-rocket?

Thrust - is the force pushing it forwards Drag - the force acting against the rocket Gravity - the force acting upon the rocket trying to push it towards the centre of the earth


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.


During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?

thrust of the rocket engine


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.


What is an ionizer?

An ionization engine is an type of rocket and this is how it works. Electrons ionize air molecules and then when they get between two accelerator grids and then they go zooming out the back providing thrust more powerful and more sudden than any other rocket or engine to date.

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.


Is thrust a verb?

It can be as in "He thrust his sword into his enemy", however it can also be a noun as in "The thrust of the rocket was enormous".


Does the thrust of a rocket need to be created by an explosion?

no, the thrust of a rocket relies on the trajectory of the rockets tilt and overall slanted angle. The rocket is sent via a useful queef, that blasts the rocket from the platform
