Which graph shows a bouncing ball? A Height Time B Velocity Time C Height Time D Velocity Time Your answer ________________ - OCR Gateway - GCSE Physics - Question 13 - 2018 - Paper 1

To determine which graph represents a bouncing ball, observe the behaviors of height and velocity over time.

A bouncing ball will have a periodic movement, where the height increases as the ball rises and decreases as it falls. This motion suggests a sinusoidal pattern in the height vs. time graph.

1. Graph A shows a decreasing height, which does not represent a bouncing ball as it continues to fall.
2. Graph B shows the velocity but does not capture the vertical motion over time adequately for a bouncing ball.
3. Graph C shows a continuous oscillation upward and downward, indicative of a bouncing ball's height changing over time.
4. Graph D shows a consistent velocity, which does not depict the nature of a bouncing ball's height changes.

Based on these observations, Graph C best illustrates the height of a bouncing ball. The graph demonstrates the periodic rise and fall characteristic of a ball bouncing.
