The horizontal component of the velocity of a projectile remains constant during the entire trajectory of the projectile.

Question

This statement is true. The horizontal velocity of a projectile is constant because there are no horizontal forces acting on the object (assuming air resistance can be neglected). This means that the object is moving at a constant speed in the horizontal direction. The vertical component of the velocity, however, is affected by gravity and changes throughout the trajectory.
