Final answer:
The object's horizontal velocity remains constant during projectile motion in an ideal scenario without air resistance, as there are no horizontal forces acting upon it after launch. Additionally, the vertical motion is independent of the horizontal motion and is influenced only by gravity.
Step-by-step explanation:
The statement "The object’s horizontal velocity remains constant while traveling" is True in the context of projectile motion without air resistance. In the absence of air resistance, an object in projectile motion maintains a constant horizontal velocity because no additional forces act upon it in the horizontal direction after it has been thrown. This means that even as the object falls under the influence of gravity, which acts vertically, the horizontal motion remains unaffected.
Furthermore, the vertical motion is independent of horizontal motion, indicating that vertical velocity is influenced solely by gravity, and all objects under the influence of gravity in freefall (subject to no air resistance) will fall at the same rate, regardless of their horizontal velocity. This concept holds true because the horizontal and vertical components of a vector are independent of one another. Therefore, an object's vertical motion does not affect its horizontal motion, and vice versa.
Note that in real-world conditions, air resistance can alter this ideal scenario, affecting both horizontal and vertical velocities of the object in motion.
