Question

Quizplus · Accepted Answer

At the top of its path, a stone thrown vertically upward has zero velocity, but its acceleration due to gravity is not zero. Gravity continues to act on the stone, pulling it back down, which is why it starts to fall back to the ground after reaching the peak of its trajectory.
