It's not possible to escape the force of Earth's gravity, no matter where
you go or how you get there. So you can just forget about that idea.
However, you CAN escape Earth. ... you can arrange it so that the force
of Earth's gravity can never pull you back to Earth. To do that, you need to
achieve a certain minimum SPEED in a direction away from Earth. The
speed you need depends on how far from the center of Earth you are.
At the surface, the speed is about 7 miles per second (25,050 miles per hour).
With any kind of engine that can accelerate you and your spaceship to the
required speed, you can slip the surly bonds of Earth, to dance the skies
on laughter-silvered wings, to climb sunward, and join the tumbling mirth
of sun-split clouds; to soar high in the sunlit silence, to chase the shouting
wind aloft, and fling your eager craft through footless halls of air; up the
long delirious burning blue, to top the windswept heights with easy grace
where never lark or even eagle flew; then to tread the high untrespassed
sanctity of space, and do a thousand things that you have not dreamed of.
What else can I help you with?
An engine with a speed that can escape earth's gravity?
An engine capable of achieving escape velocity would need to reach speeds of around 25,000 miles per hour to overcome Earth's gravity. This would typically involve using powerful rockets with sufficient thrust to propel a spacecraft beyond Earth's gravitational pull and into space. Once in space, the spacecraft would continue on its trajectory using momentum gained from the engine's initial acceleration.
Why do astronauts feel gravity in space?
There is always gravity between two objects. If the astronaut is in a stable orbit around an object, he/she will not sense any gravity. If he/she is standing on the object, such as the Moon, there will be a sense of gravity. In the case of the moon, its gravity is about one sixth that of Earth. Also, if the spacecraft is accelerating, the the reaction force of the engine will cause the sense of gravity as well.There is also gravity between the astronaut and the spaceship, but that is so small that it will generally not be noticed.
Why can astronauts not use parachutes to help slow down their spacecraft as it approaches the moon how do they slow down their spacecraft?
A parachute would not work in the vacuum of space as there is no air for it to catch and create drag. Instead, spacecraft approaching the moon slow down through a combination of a retrograde rocket burn and gravity assist maneuvers to enter lunar orbit. Mission planners carefully calculate the spacecraft's trajectory and use precise engine firings to control its speed and trajectory.
Why do engineers need to keep the mass of a spacecraft as low as possible?
The heavier it is the stronger the engine has to be. And the stronger the engine the more fuel will it burn. And the more fuel it burns the more fuel has to be carried in the rocket. And the more fuel the rocket has to lift the stronger the engine has to be.
What is Google gravity?
Google Gravity is a fun project from the developers at Mr. Doob that allows users to experience Google's search functionality in a different way. When you search for something in Google Gravity, results will appear as if they are being affected by gravity, causing them to fall and bounce around the screen. It's a playful and interactive way to explore the capabilities of web design and programming.
If a spacecraft were to go towards mars an dthe engine shut off what would happen to the pull of the planet's gravity?
If a spacecraft traveling toward Mars experiences an engine shutdown, it would continue on its current trajectory due to inertia. The pull of Mars’ gravity would begin to influence the spacecraft, gradually pulling it closer to the planet as it approaches. Depending on its speed and trajectory, the spacecraft could either enter an orbit around Mars or collide with its surface. Ultimately, the gravitational pull of Mars would become the dominant force acting on the spacecraft.
If a spacecraft is in orbit around the earth and it turns around and fires its engine to slow down?
that isn't a question, but if it did it it would get pulled to earth by earth's gravity

How does Gravity affect astronouts in space?
Gravity from objects such as the Earth, the Moon, the Sun, or the Milky Way will attract and accelerate an astronaut. "Accelerate" implies that the astronaut's velocity will change over time.If the astronaut is in free fall (basically, the spaceship's engine is not pushing the spacecraft), then the astronaut won't FEEL such gravity.

How does a particle accelerator engine work to propel spacecraft at high speeds?
A particle accelerator engine propels spacecraft at high speeds by using electromagnetic fields to accelerate charged particles to very high velocities. These particles are then expelled from the spacecraft at high speeds, creating thrust that propels the spacecraft forward.

What does a bonnet scoop do?
allows more air into the engine and engine compartment. this allows for potentially more horsepower.
What is the difference in propultion between an airplane a spacecraft?
A spacecraft need a rocket engine (which is powered by on-board oxygen and fuel) to propel itself, an airplane only needs a jet engine (which only needs on-board fuel as it uses oxygen form the air).
How is electricity made from the source gravity?
There is no clear meaning for 'source gravity' therefore I am assuming you are asking about 'electricity from gravity'. Electricity is generated by gravity through 'RC Gravity Engine' which is based on Newton's Law of Gravity, and you can find more details by searching 'thegreenushers' on any search engine. The Green Ushers is their campaign website recently launched.
