高中物理甲种本第一册189页有这样一段话:卫星发射时在加速升高的过程中,以及卫星再进入大气层向下降落的减速过程中,都有一个向上的加速度,这时就发生超重现象,此时宇宙飞行员的身体像是被一个很大的压力压住,动弹不得,想举起手来,也很困难。学生在复习这段课文时提出:卫星和人体同时处于超重时,只是人对支持物的压力增大,而人体本身的重量并不发生变化,为什么对人体产生很大的压力而动弹不得呢?对 High school physics A species of 189 pages in the first volume has such a paragraph: When the satellite is accelerated during acceleration, and when the satellite re-enters the atmosphere to slow down, there is an upward acceleration, and this happens. Overweight phenomenon. At this time, the body of the cosmic pilot was like being pressed by a great deal of pressure. It was impossible to move and it was difficult to raise his hand. When students review this text, they put forward: When the satellite and the human body are at the same time overweight, only the pressure on the support increases, but the weight of the human body does not change. Why does it exert pressure on the human body and cannot move? Correct
