Projectile's vertical velocity component changes at a constant?
Gravity... I think
Is it true that a projectile launched into space at any angle will have a constant horizontal velocity?
If space were entirely empty this would be true, but even minute gravitational forces can change the trajectory and velocity of a projectile.
How fast is a projectile moving at the top of its trajectory?
The vertical velocity is 0. The horizontal velocity is constant during the entire trajectory (and may be zero).
Is the vertical velocity of a projectile constant?
Never, since "vertical" means directly opposing the local gravity field.
What is the combination of horizontal motion with constant velocity and vertical motion with constant acceleration?
That combination is called "projectile motion". In the absence of air resistance, its shape is always a parabola.

What is the name of the curved path of a projectile that accelerates only in the vertical direction while moving at a constant horizontal velocity?
rainbow trajectory
Which of the velocity component of projectile changes and other remain constant why?
the horizontal component remain unchanged because there in no acceleration in horizontal direction
In physics when doing projectile maotion how do you find the initial velocity of the x axis?
Velocity of the x axis (how fast it's moving to the side) remains constant, so it equals whatever the x axis velocity is.
Why does the horizontal component of velocity for a projectile remain constant while the vertical component changes?
Since the velocity is constant due to the fact that there are no external forces acting in the horizontal direction, if you neglect air resistance, therefore, the horizontal velocity of a projectile is constant.
Why does the vertical component of velocity for a projectile change with time where as the horizontal component of velocity doesn't?
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
Is a projectile velocity the highest velocity that can be reached?
yes
