What really amazes me is how our understanding of free fall and gravity has changed thanks to some interesting experiments from history! Let’s take a quick look back at some important moments:
Galileo's Tower of Pisa Experiment: There’s a famous story about Galileo dropping two balls from the Leaning Tower of Pisa. He wanted to show that heavier objects don’t always fall faster. To everyone’s surprise, both balls hit the ground at the same time! This helped start the idea that all objects fall at the same rate, no matter their weight.
The Pendulum: Galileo also looked at pendulums. He discovered that the time it takes for a pendulum to swing back and forth doesn’t depend on how heavy it is. This was a big step in understanding how things move and their connection to gravity.
Newton's Law of Universal Gravitation: Then came Isaac Newton, who introduced his famous law. He said that every object pulls on every other object with a strength that depends on their sizes and how far apart they are:
This idea was a game changer! It brought together how things move on Earth and in space.
The Apple Story: There’s a tale that an apple falling from a tree made Newton think about gravity. It reminds us that sometimes the simplest things can lead to amazing discoveries.
These experiments not only helped us understand how gravity works, but they also formed the base of modern physics!
