📚 Interdisciplinary Problem-Solving in Year 9 OCR Physics | Year 9 OCR 物理：跨学科综合题型训练

Physics is not an isolated subject; it overlaps with mathematics, biology, chemistry, geography, art, and economics. In Year 9 OCR Physics, exam questions often require you to apply concepts from other disciplines, building deeper understanding and problem-solving skills. This article provides cross-subject practice problems that mirror real examination style, each explained step by step.

物理不是一个孤立的学科；它与数学、生物、化学、地理、艺术和经济学相互交叉。在 Year 9 OCR 物理中，考试题目常常要求你运用其他学科的概念，从而加深理解并锻炼解决问题的能力。本文提供模拟真实考试风格的跨学科练习题，并逐步讲解。

1. Physics Meets Mathematics: Speed-Time Graphs and Area | 物理与数学：速度-时间图与面积

In kinematics, a speed-time graph shows how the speed of an object changes over time. The area under the graph represents the distance travelled.

在运动学中，速度-时间图显示物体速度如何随时间变化。图下方的面积代表移动的距离。

Consider a car: it accelerates uniformly from rest to 20 m/s in 10 s, then travels at constant speed for 20 s, and finally decelerates uniformly to stop in 20 s. We can plot this as a trapezoid or composite shape.

考虑一辆汽车：它从静止开始
