CENCO Centrifugal Force Apparatus
This visual model illustrates rotation and centrifugal force
These two metal balls of unequal mass slide on a rod and are connected by a cord. If the rod's axis of rotation passes through their common center of gravity they will remain in place when rotated--just like the earth and moon. If the balls are unbalanced on either side, they'll drift to the dominant side. Machine-turned balls weigh 10 and 30g;rod is 22cm long. Includes complete operating instructions. Rotator required.
向心力裝置
兩顆質量不同之金屬球連接在一棒上並可在棒上移動。如果此一
棒經兩球的共同質心旋轉，則兩球在旋轉時會停留在同一位置上
----就像太陽和月亮一樣。若兩球在兩邊沒有達到平衡，則會滑至
棒的兩端。兩球各重10g和30g棒長22公分，包括完整之指導手冊。
