1. Lack of a Framework: Prior to Newton, there wasn't a robust scientific framework for understanding forces and motion. Aristotle's ideas about motion were dominant, and they didn't focus on the concept of forces as we understand them today.
2. Limited Observation: While people observed falling objects, they lacked the tools and methods to measure them accurately. They couldn't quantify the force of gravity, the relationship between mass and gravitational pull, or the effect of distance.
3. Focus on Earth-Centered Universe: The prevailing view of the universe was geocentric, meaning the Earth was at the center. This worldview made it difficult to conceptualize a force that would act across vast distances, like the Earth pulling on the Moon.
4. Misconceptions about Motion: There was confusion about the idea of inertia, which is the tendency of an object to resist changes in motion. Without a clear understanding of inertia, it was hard to separate the concept of gravity from other factors that might be influencing an object's motion.
5. Lack of Mathematical Tools: Newton's groundbreaking work on gravity relied heavily on calculus, a mathematical tool that was being developed during his time. Earlier scientists lacked the mathematical sophistication to express and analyze gravitational forces.
In summary: Earlier scientists weren't clueless about gravity; they observed it and tried to explain it. But the lack of a scientific framework, limited observations, misconceptions about motion, and the absence of sophisticated mathematical tools hindered their ability to develop a clear understanding of gravitational force. It was Isaac Newton's genius and the development of the scientific method that allowed him to formulate the Law of Universal Gravitation, revolutionizing our understanding of the universe.
