SUMMARY
When a ball is thrown vertically upward, both speed and velocity are zero at the maximum height. This is because, at that point, the ball momentarily stops before changing direction. Acceleration, however, is not zero; it remains constant at approximately -9.81 m/s² due to gravity. Understanding the distinction between speed (magnitude) and velocity (direction) is crucial in this context.
