And I mean it starts to fall immediately. Now, some of you may think that somehow the bullet’s horizontal speed prevents gravity from letting it fall. This just isn’t true. The horizontal speed of the bullet has nothing to do with how fast it falls. darty mulhouse

"WebAs an object falls, its speed increases because it’s being pulled on by gravity. The acceleration of gravity near the earth is g = -9.81 m/s^2. To find out something’s speed (or velocity) after a certain amount of time, you just multiply the acceleration of gravity by the amount of time since it was let go of.
