Correct Answer: the horizontal component of its velocity remains constant


Solution : The correct option is the horizontal component of its velocity remains constant .

During the motion of a projectile fired from the Earth's surface, the horizontal component of its velocity remains constant. No horizontal forces are operating on the projectile when it is released since there isn't much air resistance. This indicates that the projectile's horizontal velocity, which controls how quickly it goes horizontally, stays constant during flight. The projectile's initial velocity is the sole force acting on it in a horizontal direction, and until another force acts on it, it keeps moving in that direction at a constant speed.
