摘要The reason why we can still remain stationary under the action of gravity is that the ground will give us a supporting force, and this supporting force is equal to the gravity we are subjected to, and the combined force of the two is zero so there is no acceleration. But if a ball is thrown into the air, because there is nothing to support it upward, only gravity is called complete weightlessness.咨询记录 · 回答于2021-11-07为什么人们在太空中变得失重英文怎么回答您好请稍等The reason why we can still remain stationary under the action of gravity is that the ground will give us a supporting force, and this supporting force is equal to the gravity we are subjected to, and the combined force of the two is zero so there is no acceleration.
