Galileo's Ideal Inclined Plane - Quiz - Quiz Questions
Test your understanding of inertia, the relationship between force and motion, and ideal thought experiments through these exercises.
2. When the angle of the right inclined plane decreases, the distance the ball rolls to reach the original height will:
- A. Shorten
- B. Stay the same
- C. Lengthen
- D. Lengthen first then shorten
3. If the right inclined plane becomes horizontal and perfectly smooth, after release the ball will:
- A. Stop immediately
- B. Slow down to zero because there is no force to maintain it
- C. Move in a uniform straight line
- D. Accelerate
4. The key to the success of Galileo's ideal experiment lies in:
- A. The experimental equipment was very precise
- B. Observed the ball rolling forever
- C. Combining experiment with logical reasoning
- D. Using supercomputer simulation
5. True or False: Newton's First Law (Law of Inertia) is a law derived directly through experimentation.
- True
- False
6. Regarding "Inertia", which statement is correct:
- A. Only moving objects have inertia
- B. The greater the force on an object, the greater the inertia
- C. The greater the mass of an object, the greater the inertia
- D. Objects in space have no inertia
7. Why do we see rolling balls eventually stop in real life?
- A. Because there is no force to maintain its motion
- B. Because Galileo's theory is wrong
- C. Because the friction resistance received by the ball changed its state of motion
- D. Because the ball is tired
8. Design Experiment: In this experiment, if a rough wooden board is used instead of a smooth glass plate, what phenomenon will be observed?
- A. The ball can still rise to the initial height
- B. The maximum height the ball rises to is lower than the initial height
- C. The ball can rise higher
- D. The ball can't roll up at all
9. In Galileo's ideal inclined plane experiment, the ball is released without friction from a height of $h = 0.8\text{m}$. What is the speed when it reaches the horizontal plane? (Given $v = \sqrt{2gh}$, take $g = 10\text{m/s}^2$)
- A. 2 m/s
- B. 4 m/s
- C. 8 m/s
- D. 16 m/s
