At that time, people who studied science believed in Aristotle and regarded the words of this Greek philosopher more than 2,000 years ago as unchangeable truth. If anyone doubted Aristotle, people would reproach him: "What do you mean? Are you going to violate human truth?"

Aristotle:

Two iron balls, one weighing 10 pounds and the other weighing 1 pound. At the same time, when falling from a height, the 10-pound weight must hit the ground first, and the speed is 10 times that of the 1-pound weight.

If Aristotle is correct, two outcomes are possible:

If two iron balls are tied together, the slower one will drag the faster one, and the falling speed will be ___ faster than the 10-pound iron ball.

If the two iron balls tied together are considered as a whole, they weigh 11 pounds, and they will fall faster than the 10-pound iron ball.

Let your imagination take wings:

Imagine what people would say and do as people gathered around Galileo as he came down from the Leaning Tower of Pisa after his experiments. Write a paragraph with the title "After Galileo Descended the Leaning Tower", paying attention to the description of the character's language and actions.

Two iron balls, one weighing 10 pounds and the other weighing 1 pound. At the same time, when falling from a height, the 10-pound weight must hit the ground first, and the speed is 10 times that of the 1-pound weight.
