What else can I help you with?
When a rocket runs out of fuel what two forces slow the rocket down?
The same forces that had been trying to slow it down while it still had fuel, but were being overcome by the reaction force of the fuel burning in the engine of the rocket. Nothing has changed other than the loss of this reaction force, no new forces appeared.
How does a rocket get ito space if it runs out of fuel?
It doesn't.
What happens when the first stage of the rocket runs out of fuel?
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
What happens when the first stage of the multistage rocket runs out of fuel?
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
Does a rocket fall back if it runs out of oxygen?
No. A rocket does not need to fire its engines to stay in orbit. It does, however need fuel and oxygen to perform any maneuvers, so a rocket that runs out of oxygen will be stranded in space.
How does a rocket achieve maximum flight?
A rocket (firework) achieves maximum height once the fuel plus upward thrust runs out. Then gravity takes over and the rocket falls back to the ground.
How high up do rockets fly?
A rocket can reach any altitude until it runs out of fuel, provided it has enough thrust
What is a stage rocket?
That's a rocket with two stages- when the first stage (or section) runs out of fuel, it separates from the top half (second stage) and falls away, leaving that second stage to fire up, and drive the rocket higher.
What is a stage two rocket?
That's a rocket with two stages- when the first stage (or section) runs out of fuel, it separates from the top half (second stage) and falls away, leaving that second stage to fire up, and drive the rocket higher.
What is excess fuel?
The liquid that runs down the side of your car when the tank is full.
When thrust is applied in space where no friction exists to slow down a rocket wouldn't the rocket have the ability to continue accelerating indefinitely until it runs out of gas?
pretty much, yes. conditions such as soclar radiation.wind and gravity effects might make some difference, of course... and, of course, there are always Einstein's equations to be aware of - you can of course accelerate indefinitely, but only as far as some fraction of the speed of light....
A rocket fired from its launching pad not only picks up speed but its acceleration also increases significantly as firing continues Why is this so?
The speed of a rocket is dependent on the thrust of the engine, and the weight of the rocket. As the engine runs at a constant thrust, the rocket accelerates - it speeds up. But it also gets LIGHTER, because the rocket fuel that it is burning was part of the original mass of the rocket. Let's say that the rocket's "dry" weight is 100,000 pounds. The weight of the fuel alone might be twice that, or 200,000 pounds. When the rocket blasts off, it is a 300,000 pound rocket, with an engine big enough to lift a 300,000 pound weight. One second later, the rocket might have burned 10,000 pounds of fuel. So the same engine that was designed to lift a 300,000 weight is now lifting only 290,000 pounds; it will accelerate even faster. Nine seconds after that, the 200,000 pound fuel load is half gone, and the whole rocket weighs only 200,000 pounds - and you get even MORE acceleration. (But half of your fuel is gone!) And this hints at the problem with rockets; if I wanted to add another 100,000 pounds of fuel, it would probably take another 100,000 pounds of rocket to handle it. (A bigger engine, and more fuel tanks!) Now I've got a 500,000 pound rocket, but only 300,000 pounds of fuel. And the more fuel I add, the bigger the engine needs to be just to lift the weight of the fuel - and now I'm getting less and less acceleration, because of the weight of the fuel! As I increase the amount of fuel, pretty soon I'm getting no advantage at all, because ALL of the extra fuel is being used up, just to lift the extra fuel!
