A ball is thrown vertically upwards. Which of the following graphs represents its velocity-time relationship?
AStraight line with positive slope
BStraight line with negative slope
CParabola opening upwards
DHorizontal line
✓ Correct Answer: B — Straight line with negative slope
Velocity decreases linearly due to constant negative acceleration (gravity), so it is a straight line with a negative slope.
