Galileo's Great Discovery: Why Free Fall Changed Physics
Galileo Galilei's theory of falling bodies is undoubtedly one of the most influential turning points in the history of physics. In the period from the late 16th century to the early 17th century, Galileo's research on the movement of objects not only challenged the traditional concepts of the time, but also laid a solid foundation for the subsequent development of physics. Free fall is a special kind of motion, when objects move only under the influence of gravity, and Galileo's work brought our understanding of this motion to a new level.
Galileo proved experimentally and mathematically that all objects falling freely under the influence of gravity have the same acceleration, regardless of their mass.
In ancient times, Aristotle's theory of motion stated that the gravity of an object is related to its mass, and heavier objects fall faster. However, after a series of experiments, Galileo overturned this view. He used the famous Leaning Tower of Pisa experiment as an example, observing that spheres of different masses fell to the ground at the same time. This discovery showed the universality of the movement of objects.
Galileo's powers of observation and experimentalism allowed him to reveal the true nature of gravity and simplify it into a universal law of motion.
In Galileo's theory, the core of free fall motion lies in the constancy of acceleration. Over time, the object's velocity increases with the acceleration due to gravity, and this process is predictable. Galileo looked at motion in a whole new light and came up with a simple yet powerful mathematical description that was revolutionary at the time.
Furthermore, Galileo's work was not limited to free-falling motion, he also analyzed the motion of projectiles and successfully proved that their trajectories were parabolas. His research paved the way for Newton's theory of universal gravitation. It can be said that Galileo's discovery opened a new chapter for the development of physics as a whole. The mathematical methods and experimental concepts he introduced had a profound impact on later scientists.
Galileo's efforts liberated physics from previous philosophical speculation and turned it into a science that could be verified by experiments.
Over time, Galileo's theories became a cornerstone of physics education and still have a place in various modern scientific fields. Even today, the principle of free fall remains a fundamental concept in understanding motion. Whether in kinematics, dynamics or other derivative sciences, Galileo's free fall is indispensable.
When thinking deeply about Galileo's impact, we must ponder this question: what would our physics look like today if Galileo had not conducted his experiments and discoveries?
