What will happen to the speed of a space ship if it turns off its engines in space?

First of all, remember that it takes force to change the speed or direction of a
moving object, but not to keep it moving at a constant speed in a straight line.
Whatever the space ship's speed and direction are when the engine is switched off,
it continues moving at that same speed and in that same direction, until some force
comes along to change them. That force might be, for example, a gravitational one,
if the space ship's motion brings it close enough to a planet, a moon, or an asteroid.

How does the space shuttle stay in space?
The space shuttle is flying fast enough (at least 17,500 mph) which is the speed needed to stay in orbit. If it slowed below that in would fall back to earth instead of falling around it. This is basically the way it returns to earth. It turns itself around and fires it's OMS engines slowing it down enough for the earths gravity to pull it back. It then uses the atmosphere to slow it down to a safe landing speed.
How does the Space Shuttle reenter the Earth's atmosphere?
The shuttle maneuvers itself and burns it's OMS engines. This causes the shuttle to slow down to a point where the earths gravity can pull it back to earth. As the shuttle enters the high earth atmosphere it is slowed down as the atmosphere hits the craft heating it up. The shuttle then performs a series of 'S' turns slowing it down even further, until it reaches its final approach speed for landing.
What did the space shuttle use to maneuver in space?
The space shuttle had two kinds of rockets for maneuvering. The Orbital Maneuvering System (OMS) is used for changing the shuttle's orbit. When the main engines shut down, the shuttle is not completely in its orbit, so the OMS is used for final orbital insertion. The OMS is also used to de-orbit for landing. The OMS design is based on the rocket engine used by Apollo to orbit the moon and de-orbit the moon for return to earth. There are two OMS per shuttle, on the back just above the main engines. The OMS are on swivels (gimbals), which allows pointing them in slightly different directions to rotate the shuttle when they are active. When the other engines are not active, the space shuttle turns itself to point in different directions, and makes small motions such as to dock with the space station when it is already orbiting near it, using the small Reaction Control System (RCS) engines. There are 38 primary RCS engines, 14 in the front and 24 in the back, pointing in all different directions so the shuttle can move in all different directions when it is docking with something or wants to change directions. There are 6 smaller vernier RCS engines, 2 in the front and 4 in the back, that are used for fine adjustments. If the OMS engines fail, the shuttle can still de-orbit and land using the primary RCS engines in an emergency mode.
How does the space shuttle turn and what are the names of the directions of the turns?
Once in space, space shuttle orbiters use their Orbital Maneuvering System (OMS) to turn the vehicle. OMS consists of several small rocket engines are used individually or in combination to turn the vehicle where needed. This works because of Newtons third law (every action has a equal and opposite reaction). Those directions are called pitch (nose up, nose down), roll (wingtip up, wingtip down), and yaw (nose left, nose right)
Is space water?
water is not from space. People who go into space (astronauts) bring it with them and they reuse it and when they use it, they use 1 tenth of what we use now because the water turns to droplets in zero gravity. I don't know how big they are. Somebody plz tell me!
An automotive engines canshaft rotates at?
The engine's camshaft rotates at half the speed of the crankshaft. The crankshaft turns two full turns for every one full turn of the camshaft.
If a particle travels in space turns into energy or not?
Not. Because. it can only possible when it travel with speed of light, but it is still impossible.

How many pistons does a Wankel engine have?
Wankel Engines don't have pistons. They have rotors instead. The rotor is vaguely triangular, and turns in a cleverly shaped, oval chamber. The combustion volume is formed by the space enclosed between two of the tips of the rotor and the walls of the chamber. But just like piston Engines can have different numbers of pistons, wankel Engines can have different numbers of rotors.
Water in space turns into this?

How mudslides happen?
mudslides happen when heavy rain turns into mud and falls down a steep hill and turns into a mudslides.
How do you remove the governor on a 2000 Chevy Malibu?
no governor!! the ecm turns power off to the fuel pump at high speed, should happen around 104 mph
What is the mass of a man in space?
The mass of the man in space is the same as the mass of the man as he walks to board the spacecraft. Small changes do occur due to Einstein's theory of relativity. The faster the man is moving in space the smaller his mass is. As he approaches the speed of light his mass approaches zero and at the speed of light he turns into energy. Remember how they get down to planets on Star Trek. Beam me down Scotty.
What effects a roller coasters speed?
Things like descending a very tall hill or turns affect the speed of a roller coaster. Riding down the hills increases speed, and turns slow the coaster down.
The camshaft turns at what speed in relation to the crankshaft?
The camshaft turns one revolution to the crankshafts two revolutions.
What is the timing chain?
In a four-stroke overhead-cam engine, the timing chain connects the crankshaft to the camshaft. The camshaft opens and closes the valves in the cylinders and turns at half the speed of the crankshaft. Many engines now have a cog-belt instead of a chain.
