Yes, in the absence of air resistance, which is the way the situation is always
viewed by everyone except Navy gunners.
No. They're independent.
YES
For practical purposes, it means that you can calculate them independent of one another.
No, horizontal velocity and vertical velocity are independent and have no effect on each other.
The horizontal component of velocity for a projectile is not affected by the vertical component at all. Horizontal component is measured as xcos(theta) Vertical component is measured as xsin(theta) Whereas theta is the angle, and x is the magnitude, or initial speed.
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
the horizontal component remain unchanged because there in no acceleration in horizontal direction

If the initial velocity is v, at an angle x to the horizontal, then the vertical component is v*sin(x) and the horizontal component is v*cos(x).
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
the horizontal component remain unchanged because there in no acceleration in horizontal direction
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).
Because gravity is acting on the vertical component, exerting a constant -9.8m/s2 worth of acceleration.
The 'x' component of the velocity is usually the label given to the horizontalcomponent. Also, remember, we generally ignore air-resistance in this typeof exercise. When we do that, there is no horizontal force on the object, sothe horizontal component of velocity can't change.The only force on the object is gravity, and that's completely vertical, so onlythe vertical component of velocity can change.
One that goes directly up - the velocity having no horizontal component.
The force of gravity points towards the center of the earth ... the direction we call "down". The force has no horizontal component, so it can't have any effect on horizontal speed.
Horizontal and vertical components which need to be treated independently from each other when working out either the horizontal or vertical motion.
