When air resistance does not affect the motion of a projectile, its horizontal and vertical components of velocity remain constant.

False
There are many other things besides air resistance which can affect the motion of a projectile.
I could mention many things for example, however one of which is methane gas which they have observed bubbles up under the ocean waters with in the Bermuda triangle, and it has been proved that with respect to methane gas that boats sink, and air planes fall out of the sky.
Methane Gas is not air

False. If you remove air resistence, the horizontal component will be constant, because there is no friction to keep it from slowing down. However, we're not in a gravityless environment, so Earth's gravity will continue to pull the bullet down. That would change its vertical velocity, therefore its velocity is changing.

since you use the words vertical and horizontal, I assume that the projectile is being launched on or near a planet. To a fairly high orcer of precision, the horizontal velocity is constant and the vertical velocity changes significantly....but if you're on a spherical, rotating planet, neither component is really constant.

False. The horizontal component remains constant, but the vertical component does not: gravity causes it to change. Eventually, gravity will cause the projectile to strike the ground.

sounds true. one of the newtons laws i think oh it is too long since i did any thing like that though.
the horizantal velocity would remain constant or keep accelarating depending on the projectile was accelerating or not. But gravity would interfer with its vertical.

in space this would be true where there is no gravity to contend with. Here on earth, or any other planet for that matter, gravity would pull force on the projectile, sooo...
FALSE

False. Your statement does not take in the effect of gravity, which means it will not remain constant.

False, you still have gravity, or magnetic forces to deal with.
