Default Something I always wondered about...

Here's a bullets journal, taken from a Jack Reacher novel:

And it had dropped seven inches. Gravity had pulled it in. The more gravity
pulled, the more the bullet slowed.


Ummmm, no. Gravity does *not* cause the bullet's horizontal velocity to decrease.

The more it slowed, the more gravity deflected it.


Ummmm, no. The longer it was in flight, the more gravity deflected it. Vertical motion due to
gravity depends only on the length of time that it's been in motion, and is *not* affected in the
least by horizontal velocity. A bullet fired from a gun parallel to the ground, and a bullet
*dropped* from the same height, will strike the ground at the same instant.
