当宇航员乘坐宇宙飞船出发时,他们会被一股六倍(无人时可达十倍)于地球重力的力按在座位上,即变成人原重的六倍。现在咱们减半,如果你受到一个三倍于地球重力的力,你认为自己还能够移动吗?你需要:体重秤,毛巾,4~5本厚词典,1个大勺子,3个玻璃球。第一步:把体重秤放在桌子上,坐在秤的旁边。第二步:把玻璃球放在勺子里,拿着勺子上下移动。第三步:拿着勺子,把胳膊肘放在秤上。 When astronauts depart on a spaceship, they are six times as powerful as Earth’s forces of gravity on the seat, six times (no more than ten times). Now that we halve, do you think you can move if you are subjected to three times the force of gravity on earth? You need: scales, towels, 4 to 5 thick dictionaries, 1 big spoon and 3 glass balls. The first step: the scales on the table, sitting next to the scale. The second step: the glass ball on the spoon, holding the spoon to move up and down. The third step: Hold the spoon, put the elbow on the scale.
