Question

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.

Answer 1

Vertical velocity decreases.

Step-by-step 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

`v(t)=v_0 -gt`

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