what happens when we fire bullet in space?

Question

please tell the type of motion and the end of motion.

Answer 1

Pretty much the same thing that happens when it's fired here on Earth. There is no real air in space to slow it down so it won't undergo friction due to that. There is still gravity in space so it's trajectory wouldn't really be a straight line.

The shooter would not be propelled with the same velocity of the bullet. When fired, equal amounts of energy are imparted on the bullet and the gun (and since it is held by a person, the person too). The bullet is pushed one way and the gun/person the other. However the bullet has much less mass than the gun/person so it will fly much faster with the same amount of energy. The recoil force on you would feel no different than it would on Earth. However, since you're not standing on anything to brace yourself, it might cause you to begin rotating backwards slowly.

Gunpowder does not need oxygen in the air to ignite. It contains its own oxidizer so the vacuum of space would not prevent firing of the gun. A gas operated semi-automatic firearm may not cycle properly due to the lack of air pressure to cycle it however.

Answer 2

It would travel in a straight line,after reaching terminal velocity, possibly forever, until either gravity from another body draws it to itself or it strikes something to stop it. Remember Newtons laws concerning bodies in motion. Hope this helps,Mark P.S. The bullet WILL fire,Bombs are sealed too and do explode before they are exposed to O2.

Answer 3

it extremely is going to hearth exact, contemporary gun powder supplies its own oxidizers. Its muzzle speed may well be in basic terms extremely larger than in the international, assuming the gun is held in place and not allowed to back up lots because of fact there's no air resistance. Whoever shoots it must be nicely anchored. The bullet will today run into something because of fact bullets shuttle at ridiculously sluggish speeds whilst in comparison with maximum astronomical bodies and characteristic ridiculously low mass besides. So it extremely is going to definitely and today be captured. If whoever fires the shot isn't anchored in any respect she or he would be pressured backwards at an extremely low speed and just about actual be tumbling. The bullet accordingly might bypass away the muzzle at a lots decreased speed. the load of the gun and astronaut could have in basic terms as lots shared push (potential from the firing) in them because of fact the bullet does. What imparts the potential (here, speed) to the bullet is the stress of the gun, how little it extremely is authorized to take a seat back. Un-anchored the released potential is shared frivolously. because of fact the mass of the gun and astronaut is many circumstances greater desirable than that of the bullet the astronaut will pass lots slower than the bullet however the bullets speed would be in basic terms a fragment, a tiny fraction, of its widely used muzzle speed. (the cost assessment gets worse once you attempt to comprise the potential utilized in tumbling besides as pass of the completed tumbling physique in some course. in case you already know the load of the astronaut and pistol and all of his kit, and the load of the bullet you may certainly make a coarse estimate of the comparable speeds. in case you already know the muzzle speed you'll be able to make an estimate for the cost of the bullet yet attempting to get the cost of the astronaut may well be just about impossible without creating quite a few assumptions, how lots potential is used up interior the three axises of rotation.

Answer 4

It will go into orbit, affected by whatever planets are around it.
If it is near a planet (such as the Earth), and the orbit brings it into the atmosphere, then maybe it will burn up from air friction.

Or maybe it will go back into space, or maybe it will crash into the planet.

Orbits, without air friction, are in the shape of ellipses. But if there is gravity from two or more planets or moon, then it is not elliptical orbit.

Answer 5

Combination of 2 and 3, they are both right. Firing the gun would make you fly backwards, and in space it wouldn't stop until it either hit something or was captured by gravity of an object.

Answer 6

Well if there is no force to act upon it it will continue at a constant speed in a constant direction. But there are a lot of things in space that can act upon it (much lees then on the earth) such as gravity, objects, ect.

Answer 7

If you are in orbit and fire it in the direction of orbit it will spiral away from the earth.
The muzzle velocity will be greater than on earth due to lack of air pressure.
Unless it hits something there is no reason for it to ever stop.

Answer 8

If a bullet were fired in space the force of the blast will not only cause the bullet to propel forward, but the shooter will be propelled backwards with the same velocity as the bullet. This is due to one Newton's Laws of physics, for every action there is an equal but opposite reaction.

Answer 9

first of all... as far as I know a gun could never be fired in space (no air for propulstion) but if it could....
an object in motion stays in motion unless acted upon by an outside force such as friction from gravity and atmosphere, or a semi solid object. in space there is no gravity or atmosphere to stop a projectile... and it would continue on forever until it hit something which could potientially be for thousands of years.

Answer 10

if it fired it would probably go till it hit something, but int order to fire the gun powder you need oxygen and there is no oxygen in space so it might not even fire
