# Does gravity affect a bullet?

## Does gravity affect a bullet?

In small arms external ballistics applications, gravity imparts a downward acceleration on the projectile, causing it to drop from the line of sight. Drag, or the air resistance, decelerates the projectile with a force proportional to the square of the velocity. Wind makes the projectile deviate from its trajectory.

## Can a bullet explode in space?

Yes. Bullets carry their own oxidising agent in the explosive of the cartridge (which is sealed, anyway) so there’s no need for atmospheric oxygen to ignite the propellant. Once shot, the bullet will keep going forever, as the universe is expanding at a faster rate than the bullet will travel.

How fast would a bullet move in space?

Those galaxies are travelling at around 200km/s (124 miles/sec) as the Universe expands, whereas a travelling bullet can reach speeds of only 1km/s (0.62 mile/sec).

### Why is bullet trajectory important?

Determine the height of a suspect based upon the bullet trajectory. Bullet analysis or ballistics is an integral component of forensic science. allows scientists to determine what kind of gun was used, the distance the shooter was from the bullet hole as well as the height of the shooter.

### What is the probable shape of a gunshot wound if the target is hit on 90 degrees angle?

ellipse
As mentioned previously, the only way a round bullet hole will be produced is if the gun is directly against the target at a 90° angle, otherwise, the hole will be an ellipse.

What causes a loud sound when a gun is fired?

Well, as mentioned earlier, a bullet is powered by a tremendous amount of pressure at its back, which propels it forward. Therefore, after the bullet exits the barrel, the pressure of the explosion (that occurred in the back) is suddenly released. This is the reason there’s such a loud BANG when you fire.

## Why does a bullet go faster in space than on Earth?

This additional contribution by gravity means the bullet can be going faster when it hits the ground than it was when it left the muzzle of the gun. So: instantaneously after firing, the speed of a bullet in space and on earth should be the same.

## How does gravity affect the speed of a bullet?

The fact that one bullet was traveling horizontally at 3,000 fps has no effect on that bullet falling due to gravity. The speed of the bullet, however, does have an effect on how much the bullet falls before it hits a certain target because of the time it takes to get to the target. Objects fall due to gravity at an acceleration rate of 9.8 m/s^2.

Can you shoot a bullet in zero gravity?

The speed of the bullet would remain roughly the same in zero gravity as it is on Earth, so shooting in space is not going to make your gun any more or less lethal to your space enemy. The only way you’d see a noticeable difference is if you were firing the bullet over a long distance.

### What happens if you shoot someone in the back in space?

According to Schultz, if the bullet is shot straight toward Jupiter, the planet’s gravity will accelerate the ammo to the eye-popping speed of almost 60 kilometers per second by the time it crosses the gas giant’s threshold. Shooting someone in the back is a cowardly act.
