The image depicts a velocity-time (v-t) graph illustrating the changes in velocity over time. The graph is a smooth curve with labeled points A, B, C, D, and E. - **Axes**: The vertical axis (y-axis) represents velocity (v), and the horizontal axis (x-axis) represents time (t). - **Curve Behavior**: - The curve starts above the horizontal axis, showing a positive velocity. - It reaches a maximum point at **A**, which indicates the highest positive velocity. - Moving from **A** to **B**, the velocity decreases, indicating deceleration. - At **B**, the curve continues to slope downwards, showing further deceleration. - At point **C**, the curve crosses the horizontal axis, indicating a transition from positive to negative velocity. - The curve then dips further below the axis, reaching a minimum point at **D**, indicating the highest negative velocity. - After point **D**, the curve begins to rise, moving towards zero velocity. - At point **E**, the curve is still below the axis but starts ascending, showing a decrease in negative velocity. This graph represents a wave-like motion, suggestive of oscillatory or periodic velocity changes. The transition points (crossing the horizontal axis) at **C** and **E** indicate moments when the velocity is zero, signaling a change in direction.
