In the simulation above, as the projectile travels upward, how does the vertical velocity change? question 9 options: vertical velocity increases. vertical velocity remains the same. vertical velocity is zero. vertical velocity decreases.

Vertical velocity decreases.

Explanation:

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

- a horizontal motion, with constant velocity

- a vertical motion, with constant acceleration g=9.8 m/s^2 towards the ground

In the vertical motion, there is a constant acceleration directed downward: this means that the vertical velocity decreases as the ball goes higher. In fact, it decreases following the equation

And it decreases until the ball reaches its maximum height, then it starts increasing again.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
