In reference to "Can I fire a gun on the moon? First, we know that the bullet has the same initial velocity on the Moon as it does on the Earth - that is, it exits the gun at the same speed. But as soon as it leaves the gun, it's a different story. First, the Moon bullet doesn't have to contend with air resistance. With so little friction, it can maintain its speed longer than the Earth bullet can.
It's analogous to shooting a hockey puck across ice, which has very little friction, and shooting across sand, which has a lot of friction. The puck will travel a lot farther on the ice! Now, there is the issue of gravity.
Assuming your bullet doesn't hit anything a pretty safe bet on the Moon, but don't try this on Earth! You can use some basic physics to figure out how far the bullet will fly horizontally and vertically.
It turns out that the bullet's horizontal range - the total distance it travels before gravity wrestles it to the ground - is Buenas Noches - Various - Musical Productions All Stars by the equation:. On Earth, it is 9. To find g on the Moon, we need another equation:. G is the gravitational constantM is the mass of the Moonand R is the radius of the Moon.
Anyway, on the Moon. So, neglecting air resistance, the bullet will go about 6 times farther on the Moon than on Earth. Once you take air resistance into account, the Moon bullet has an even bigger advantage! You might also ask, if the bullet were fired straight up, could True Love - Prins Carl - No Mercy actually escape the moon's gravitational pull and fly off into space?
To answer this, we have to compare the moon's "escape velocity" the minimum velocity an object needs to escape the Moon's gravity to the bullet's initial velocity.
The moon's escape velocity is about 2. So take cover - even in this case, what goes up must come down!
