Description

"Experiment on the Leaning Tower" PPT courseware 2

Galileo Galilei, an Italian physicist and astronomer, advocated that systematic observation and experiments must be carried out to study the natural world. He was one of the founders of modern experimental science and mechanical materialism. Through experiments, it established the law of free fall. He also discovered the law of inertia of objects, the isochronism of pendulum vibration, the laws of projectile motion, and determined Galileo's principle of relativity. He is therefore considered a pioneer in classical mechanics and experimental physics.

learning target:

1. Learn from scientists’ spirit of exploration and innovation.

2. Understand the relevant knowledge involved in the text and enrich the knowledge background.

3. Learn the clever ideas of articles.

Analyze the title:

1.What kind of leaning tower is this? Where?

2. Who is going to do the experiment here? Why do this experiment?

3. What experiment was done? What are the results of the experiment?

4. What problem does this experiment want to prove?

The Leaning Tower of Pisa is in the ancient city of Pisa in western Italy. Built in 1174. The tower has a total of 8 floors and is 54.5 meters high. When the tower reached the third floor, it was discovered that the foundation began to tilt. When the entire tower was completed, the centerline of the tower top had deviated from the vertical centerline of the tower by about 2 meters. Because the tower "slants but does not collapse", it is famous. In 1590, Galileo performed a free fall experiment on the tower, making the Leaning Tower of Pisa even more famous.

overall perception

At the end of the article, it is written about Galileo's experiment on the Leaning Tower of Pisa and the discovery of the law of free fall. What discovery did he talk about at the beginning? What is written in the middle?
