Questions 10
Question 1
What was Galileo trying to prove by dropping cannonballs from the Leaning Tower of Pisa?
Answer: He wanted to test whether objects of different masses fall at the same rate.
Question 2
According to Galileo’s findings, in the absence of air resistance, how do objects of different masses fall?
Answer: All objects fall at the same rate.
Question 3
Which of the following best describes Galileo’s method of investigation?
Answer: He used mathematical analysis and experiments.
Question 4
In Galileo’s time, what was revolutionary about his approach to studying motion?
Answer: He used controlled experiments to test hypotheses.
Question 5
What conclusion did Galileo reach about the acceleration of falling objects?
Answer: It is constant for all objects near Earth’s surface.
Question 6
Why was the Leaning Tower of Pisa experiment significant?
Answer: It publicly challenged Aristotle’s long-held ideas.
Question 7
What role does air resistance play when objects fall on Earth?
Answer: It slows down objects with a larger surface area more than compact ones.
Question 8
Which famous demonstration showed Galileo’s principle in action on the Moon?
Answer: US astronauts dropping a feather and a hammer during Apollo 15
Question 9
Why did the Apollo 15 feather-and-hammer experiment produce the same results Galileo predicted?
Answer: There is no air resistance on the Moon.
Question 10
What happens when you drop a feather and a bowling-ball inside a vacuum chamber on Earth?
Answer: Both fall together at the same rate.
