解释这张图的知识点，结合生活中的实例。---**Chart Title:** 高度-时间关系 (Height-Time Relationship) **Chart Type:** Line chart **Axes:** * **X-axis:** * Label: 时间 (秒) (Time (seconds)) * Scale: From 0 to 10 * **Left Y-axis:** * Label: 高度 (米) (Height (meters)) * Scale: From 0 to 120 * **Right Y-axis:** * Label: (Implied Velocity) * Scale: From -40 to 40. The 0 value on this axis is aligned with the 60 value on the left Y-axis by a dotted line. Units are not explicitly labeled but are likely meters per second (m/s). **Lines:** * **Blue Solid Line:** * Represents: 高度变化 (Height change) (from legend) * Description: Parabolic curve, starts at (0, 0), reaches a maximum, and ends around (10, 0). * **Red Dashed Line:** * Represents: 速度变化 (Velocity change) (from legend) * Description: Straight line with negative slope, starts at a positive value (~40) at time 0, decreases linearly, crosses the x-axis (or right Y-axis zero line) at time 5.0s, and reaches a negative value (~-40) at time 10s. **Annotations:** * A red filled circle is on the blue height curve at its peak. * Text annotation pointing to the red circle: * 最高点: 122.5m (Highest point: 122.5m) * 时间: 5.0s (Time: 5.0s) **Other Elements:** * **Legend:** * Blue solid line: 高度变化 (Height change) * Red dashed line: 速度变化 (Velocity change) * **Dotted Horizontal Line:** Located at Height = 60m on the left Y-axis scale, corresponding to 0 on the right Y-axis scale.
