Question

what did taking measurements reveal about the velocity of the fireball? Was the fireball’s velocity constant or changing?

Answer 1

The fireball slows down when moving upward. It speeds up when moving downward. So, its velocity is always changing.

Answer 2

The fireball went in the air and slowed down. This is because, the gravity holds us down on earth and if not, we would be floating everywhere. So, the fireball slows down because the gravity is pulling it back down. As well as it's going down, it becomes faster. Just like when we jump, we come down pretty fast. So, when the gravity pulls you down and you go down it starts to pick up speed. Thats just how gravity works.
