When a ball is thrown straight up, its velocity initially points upward as it ascends. However, due to gravity, its acceleration is always downward, towards the center of the Earth. This downward acceleration slows the ball until it reaches its peak, where its velocity is momentarily zero, before it starts to fall back down, accelerating under gravity.
