Question

In the absence of air resistance, why does the horizontal component of velocity for a projectile such as a

bullet remain constant while the vertical component changes?

Answer 1

Step-by-step explanation:

The vertical velocity changes because gravity is what brings the ball downwards, since gravity is what cause acclereation in free fall, acclereatiin will make the velocity become more negative.

There is no force happening on the ball in the horinzontal direction so according to Newton 1st law, the ball will remain in constant velocity n the horinzotnal direction.
