Speed doesn't create artificial gravity. Acceleration does. That means change of speed.
That's why you feel heavier when the elevator starts up, and lighter when it starts down.
And it's why you feel a force (like gravity) pushing you back into the seat when the car starts forward,
and a force (like gravity) pulling you forward out of your seat when the car slows down.
As long as the spacecraft (or car) is speeding up, there will be a force (like gravity) pulling backwards.
As long as the spacecraft (or car) is slowing down, there will be a force (like gravity) pulling forward.
If the spacecraft (or car) goes 32.2 feet per second faster after every second, then the force
will have the same strength as earth's gravity.

How fast did Apollo 8 travel?
The speed of an Apollo spacecraft is hard to answer because there are many answers available. The best question would ask something like "What was the maximum speed?", or "what was the average speed during the translunar or transearth phase?" The problem is that the speed of spacecraft was constantly changing. In order to break out of Earth orbit and reach the moon, an object must travel approximately 24,000 miles per hour. The Apollo spacecraft did just that. However, they didn't maintain that speed. Once they were out of orbit, they simply coasted the entire distance to the moon. Breaking out of Earth orbit does not mean breaking free from Earth's gravity though. The Earth was constantly pulling on the spacecraft, slowing it down. Eventually, the spacecraft got close enough to the moon that that moon's gravity had a stronger effect than the Earth's gravity, pulling the Apollo module forward, causing the module to speed up. With that in mind, we can provide the speed of Apollo 8 at various events: At translunar injection, Apollo 8 was traveling at 35, 505.41 ft/sec, or 24,208 mph. When the spacecraft entered the moon's sphere of influence (when the action of the moon's gravity became stronger than the action of the Earth's gravity on the spacecraft), it had slowed down to 3,261 ft/sec, or 2,223 mph. When the spacecraft reentered the Earth's atmosphere after returning from the moon, it was traveling at 36,221 ft/sec, or 24,696 mph.
How do saterlites orbit?
Artificial or natural; they're falling. One definition of flying is to throw yourself at the ground and miss. All these objects are doing just that. (including the Earth in its path around the sun) As an example: you know that the Earth is curved. You fall towards it due to gravity. If you move fast enough (to orbit) then you have to move fast enough so that the surface of the planet falls away AS FAST AS you are falling due to its gravity.
How fast can a man made spacecraft travel in outer space?
Man-made spacecraft can travel at speeds up to about 17,500 miles per hour (28,000 kilometers per hour) in outer space. This speed allows spacecraft to escape Earth's gravitational pull and travel to other planets, moons, and even beyond our solar system.
How fast did the Apollo spacecraft go?
The Apollo spacecraft traveled at speeds of about 25,000 miles per hour (40,000 km/h) to reach the Moon and during its return journey to Earth.
How fast was the Apollo ship flying to the moon in mph?
The Apollo spacecraft traveled to the moon at an average speed of around 36,000 mph. This incredible speed was necessary to escape Earth's gravity and reach the moon's orbit in a relatively short time.
How does gravity affect the space station?
The International space station is constantly falling towards Earth under the pull of Earth's gravity (Just like any other object - gravity does not stop when you reach space!). However the Station is moving very fast horizontally and, as the Earth is a sphere, this means that as it falls its path takes it round the Earth in a circle - it is in "orbit". This means that if you are in the space station you are falling as fast as gravity can pull you and therefore you do not feel the pull of gravity, making you weightless.
How do you create artifical gravity?
So far there is no such thing (that the common people know of) that can create it, only simulate it, i.e. moving so fast it generates the feeling of being weightless.
What design challenges do scientists face in trying to land a spacecraft on a comet?
the speed of a comet and the rotation is far too fast for a spacecraft to land
How fast do you have to go for gravity not to take hold of you?
Speed does not matter- gravity will still have a pull.
How fast was the Galileo spacecraft going when it reached Jupiter?
From what I have read it was going 50,000 mph.
What keeps the moon and artificial satellites in orbit around a planet?
Inertia. The moon is constantly "falling" towards Earth, but it's also moving sideways so fast that it constantly misses and therefore remains in orbit.

How can you stay on earth when moving so fast?
Gravity.

Why did the Apollo 13 spacecraft have a parachute?
The same reason why all spacecrafts have parachutes: During reentry into the Earth's atmosphere, the spacecraft goes extremely fast. And if there are people in the spacecraft and no parachute, they would slam into the water at that speed and it would be like hitting concrete. So without a parachute, everyone on the spacecraft would be killed.
