ANSWER;

1. Why does the vertical component of the projectile's velocity vary with time?

- Because the force of gravity on a projectile acts only vertically, hence only the vertical component of a projectile changes with time.

2. Why does the horizontal component of the projectile's velocity independent of time?

- Because The horizontal motion of a projectile is independent of its vertical motion.

3. In the physical world, why do you think vertical and horizontal components of projectiles occur? Give examples

- Because the horizontal and vertical motions of a projectile are independent, meaning they do not affect each other.

4. A baseball is thrown horizontally with an initial velocity. Describe its path and overall motion if there is no gravity

- Without gravity, the ball continues in a straight line at its initial velocity forever, or until it happens to collide with some other object in its path.

5. A baseball is thrown horizontally with an initial velocity. Describe its path and overall motion if there is gravity

- With gravity, the ball will drop vertically below its otherwise straight-line, inertial path.
