Before we left,Li Yanping explained to me that the force of gravity would change three times on our journey a

As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earths gravity.It was so hard that we could not say anything to each other. Gradually the weight lessened and I
11、was able to talk to him.“Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground.” I asked.“We are too far from the earth now to feel its pull,” he explained,“so we feel as if there is no gravity at all. When we get closer to the moon, we shal

14、 on,” I said.“If you are right, my weight will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!”I laughed and climbed down the steps from the spaceship. But when I tried to
