ニュートンの第２法則？ Newton's Second Theorem? ●パイプ編 金属パイプだとゆっくり落ちる！？ パイプの材料の違いが関係してるのかな？それともおもりの中に何か入っているのかな？ ●募金箱編 １円玉はアルミニウムだから磁石に付かないはずのに、どうして磁石にはじかれるのかな？ Try the tubes: Do you think the weight will drop slowly with the metal tube?Do you think the material used for the tube has something to do with the dropping speed?Or do you think there is something inside the weight that differs the dropping speed? Try the collection box: An 1 yen coin is made of aluminium, so it doesn't react to magnets. Why are they refused by the magnet? 3本のパイプ 磁石が一番遅く落ちるのは？ Now with these three tubes, which do you think that allows the magnet drop slowest of all? ▼マウスをあててみよう！ アルミパイプ ▼On mouse here! The aluminium tube. 金属のそばを磁石が動くと、その磁石の反発する向きに磁力が発生する電磁誘導について体験します。
