第91集《地心引力的实验》
# � **科学知识点总结** **1. 自由落体的基本原理** * 在真空中,任何物体下落速度一致,与重量无关。 **2. 空气阻力(Drag)** * 表面积、形状和表面粗糙度会影响空气阻力大小。 * 粗糙表面会形成湍流,降低阻力,使物体落得更快。 **3. 表面纹路的科学应用**

� **科学知识点总结** **1. 磁悬浮原理(磁力平衡)** * 物体能悬浮,是因为磁场上下“推力”刚好平衡重力。 * 任何外界磁场都会破坏平衡。 **2. 热影响磁性(居里点原理)** * 金属受热会改变磁性,温度升高会让磁场变强或变弱。 * 热水保温杯成了“不小心的磁场源”。 **3. 弱磁干扰**

学校新建的“校园能源塔”——一座利用太阳能和风能供电的装置,突然在夜晚闪烁异常,电表数值急剧上升。有人怀疑被人偷电,少年科学探案队却从风叶的声音里发现了秘密。

学校新来的智能机器人助手“小贝”突然在夜里失踪,监控画面显示它竟“自己走出了实验楼”。少年科学探案队决定查清——这是真正的“机器人逃跑”,还是一个程序错误引发的误会?

一天清晨,校园广播突然自动播放奇怪的语音,还模仿老师的声音点名学生!所有人以为系统被黑客入侵。少年科学探案队怀疑,这可能是AI语音系统的“幻听”反应……


学校实验室的智能冰箱突然故障,里面储存的生物样本险些全部融化。可奇怪的是——每到晚上十点,冰箱自己会“启动”几分钟。少年科学探案队决定揭开背后的电路秘密。

一连几天,镇子上夜空中都出现了奇怪的闪光。人们以为是流星,但小宇发现那闪光的节奏太有规律了。少年科学探案队决定找出——这究竟是自然现象,还是某种人造信号?
