It would keep moving at a constant speed in the same direction forever, or until it hits another object.

Gravity would be pulling down on a projectile object.
That would be a projectile.
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.

Without gravity, everything would float away into space, including our atmosphere and the water on Earth. Without gravity, there would be no force holding objects together, and planets would not be able to orbit the sun. Life as we know it would not exist without gravity to create the conditions necessary for it.
without gravity there, the planet would float off in a line. it would keep going until a force stops it so says newtons 1st law of motion.
Without gravity, everything on Earth would float off into space. There would be no atmosphere or oceans, and all living things would have a hard time surviving without the necessary conditions for life. The absence of gravity would also disrupt the orbits of celestial bodies, leading to chaos in the solar system.
In zero gravity, buoyancy would not be present as there is no gravity to create the force that causes objects to float in a fluid. Objects would not experience an apparent weight loss or loss of buoyancy in zero gravity.
The vertical motion of a projectile is known as free fall motion. The projectile initially moves upwards against gravity, slows down, stops, then accelerates downwards due to gravity. This motion is independent of the horizontal motion of the projectile.
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
Yes, a sky would still exist even without gravity. Gravity is what holds our atmosphere close to Earth, but even without it, the atmosphere would still exist and interact with light to create the appearance of a sky.
