It would keep moving at a constant speed in the same direction forever, or until it hits another object.
Yes. Gravity acts downward on a projectile. That is why on Earth, objects eventually start to come down after throwing them, without the force of gravity acting downward the object would continue in a straight line forever.
Gravity would be pulling down on a projectile object.
It would become a null concept. ... "without meaning"
That would be a projectile.
Weight would not exist without gravity.
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.

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.
No, as there would be no coalescence of matter to form suns and planets without gravity.
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.
eating with no gravity?
