Question

In the simulation above, as the projectile travels downward, how does the vertical velocity change?

Answer 1

The vertical velocity increases.

The vertical velocity increases because of acceleration due to gravity. The horizontal velocity neither accelerates nor decelerates.

Hope this helps!!

Answer 2

The vertical velocity increases

Step-by-step explanation:

The motion of the ball is the motion of a projectile, which consists of two independent motions:

- a horizontal motion, with constant velocity

- a vertical motion, with constant acceleration (g=9.8 m/s^2) directed downward

When the ball is travelling downward, its vertical velocity is directed downward. The acceleration is in the same direction (downward), so the vertical velocity is increasing.
