the horizontal component remain unchanged because there in no acceleration in horizontal direction

Projectile's vertical velocity component changes at a constant?
Gravity... I think
Which velocity component changes along the path?
The motion of a projectile is a combination of two motions, a constant speed motion in the horizontal direction, and an accelerated motion in the vertical direction. The velocity component that changes along the path is Vy.
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.
Can the velocity of a car which is turning a curve be held constant?
The speed can be constant but the velocity can't, because the directionof motion ... which is a component of velocity ... is changing. Also the velocity of a moving body changes when its speed changes but remains moving towards the same direction ... :) :]
Does velocity of an object remain constant in uniform circular motion?
Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.

What is the horizontal acceleration of a projectile as its position changes?
In the usual simple treatment of projectile motion, the horizontal component of the projectile's velocity is assumed to be constant, and is equal to the magnitude of the initial (launch) velocity multiplied by the cosine of the elevation angle at the time of launch.

Velocity is a vector with magnitude (speed) and direction. Since the linear velocity changes direction the speed is constant but the velocity is NOT constant.
If the instantaneous velocity of an object remains constand can its instantaneous speed change?
No. Speed can remain constant when velocity changes, but velocity can't remain constant when speed changes.
Is the velocity constant if a car is going around a curve?
NO,velocity changes.
Does constant speed give you constant velocity?
No. The speed can be consant but direction can change and thus the velocity changes.
When you run around a track at 5 km h your velocity is constant?
No. Your speed is constant but your velocity is not. Velocity is a vector and as you run around a track, the direction of your motion changes and so the velocity changes - not in magnitude but in direction.
What is the trajectory of the projectile?
An "ideal" projectile trajectory ... without the influence of wind or air resistance ... is a section of a parabola. That's the figure you get when the horizontal position changes at constant speed and the vertical position changes at a speed that is itself changing at a constant rate.
Why is it an object can accelerate while travelling at constant speed but not at constant velocity?
Acceleration means the velocity changes. Velocity is made up of speed and a direction, so if only the direction changes, the velocity still changes, and therefore there is acceleration. The typical example is moving around in a circle.
