📖 英文原文
Long jump is a sport combining athletic skill with basic physics. When athletes sprint down the runway, they turn horizontal speed into upward lift at take-off. The ideal take-off angle is around 20 degrees. Too steep an angle wastes forward speed; too flat reduces airborne time. During flight, athletes use different techniques such as the hang style to keep their body balanced. Wind conditions also affect the final mark. A tailwind within the allowed limit can help jumpers go further. Top athletes spend time analysing video data to adjust tiny details of their movement.
📝 中文翻译
跳远是一项融合运动技巧与基础物理原理的项目。运动员沿着跑道冲刺，在起跳时把水平速度转化为向上的升力。理想起跳角度大约20度。角度太陡会浪费向前的速度，角度太平则缩短腾空时间。腾空阶段，运动员会采用挺身式等技术保持身体平衡。风向条件同样影响最终成绩，规则允许范围内的顺风可以帮助选手跳得更远。顶尖运动员会分析录像数据，微调动作细节。
