SUMMARY
The discussion clarifies that the concept of displacement when throwing a ball upward is dependent on the chosen coordinate system. It establishes that one can arbitrarily define the positive direction, either upward or downward, without affecting the physical results, as long as the convention is consistently applied. For instance, when throwing a ball from the ground upward, the upward direction is typically defined as positive, while throwing from a tower may result in negative displacement if downward is defined as positive. The force of gravity is considered positive when the displacement is negative during upward motion.
