Question
A ball is thrown vertically upward into the air. Which of the following acceleration-time graph represents the ball's motion? Assume down is positive.
Answers
GPT 3.5
The correct acceleration-time graph for the ball's motion when thrown vertically upward into the air is Option A.
In this graph, the acceleration is initially positive as the ball is moving upwards against the force of gravity. As it reaches its peak height, the acceleration becomes zero since the ball momentarily stops moving before starting to fall back downwards. As the ball falls back downwards, the acceleration becomes negative as gravity pulls it downwards. Option A accurately illustrates this change in acceleration from positive to zero to negative.
