In space there is no air resistance, so no force slowing the rocket down. Once in orbit round the earth it will continue indefinitely without using its engine. It would go in a straight line but the earth's gravity makes it stay in orbit. If it is further accelerated out of orbit by the rocket motor it will start to leave earth but eventually come to a point where the gravity from another body such as the moon is stronger and then it will accelerate towards that body, again without needing to use the motor. The motor is only needed to change speed, not to continue at the same speed, or to simply react to gravity forces.
What else can I help you with?
Why doesn't a rocket in space need to use an engine to keep moving in space?
Because there is no friction in space to slow the rocket down. Once the rocket is at its cruising speed, the engine can be switched off. Of course, that means that you have to use a different engine (pointing forwards) to slow down and stop the rocket since friction won't do it for you.
Why wouldn't you hear the roar of a rocket engine in space?
Space is essentially a vacuum. Sound needs a medium to travel through to be heard. Therefore the sound of a rocket engine cannot be heard in space.
What keeps the probe moving in space after the rocket no longer pushes it?
Inertia.
Why is nasa moving back to space rocket instead of space shuttle?
It is cheaper and more efficient.
Does a rocket have an engine?
yes, a rocket does have a engine. the engine is the horse power to a rocket that gets it to go... and keep going... and keep going. as long as it has a good engine then it would be a pretty long ride in to space.
What happens when you jump out of a rocket in space?
If you were to jump out of a rocket in space, you would continue moving in the same direction and at the same velocity as the rocket due to inertia. Without any external forces acting on you, you would float alongside the rocket in the vacuum of space.
What does the engine do on a space rocket?
Provide thrust ... which changes velocity.
What happends to fule after it leaves the rocket in space?
The fuel, spelled F-U-E-L, is burned or autocombusts (in the case of hydrazine), and the exhaust shoots out of the rocket engine, propelling the rocket in the opposite direction. After it leaves the engine, it spreads out into space.
Can you use petrol as a fuel in rocket engine?
Rocket fuel contains oxygen, which is not found in space. A rocket in space could theoretically work in space if it were to carry its own oxygen, but other fuels such as hydrogen are more efficient.
During a rocket launch whioch is greater thrust of the rocket engine or weight of the rocket?
During a rocket launch, the thrust of the rocket engine is greater than the weight of the rocket. This is necessary for the rocket to overcome Earth's gravitational pull and lift off into space. The thrust generated pushes the rocket upwards while gravity pulls it down.
How the rocket stay in space and aeroplane can't stay in space?
The engine on the plane is not as strong and big as the rocket Also the pressure could destroy the plane into pieces
A space probe may be carried by a rocket into outer space what keep the probe moving after the rocket no longer pushes it?
Once the rocket stops pushing the probe, it continues moving due to its inertia. In the vacuum of space, without any air resistance to slow it down, the probe will keep moving at a constant velocity until acted upon by another force, such as gravity from a celestial body or a thruster on the probe itself.
