Isaac Newton made discoveries that changed how people looked at the natural world. He challenged many beliefs that existed before him in some important ways.
Challenging Old Ideas: Before Newton, many people believed what Aristotle said—namely, that heavier objects fall faster than lighter ones. Newton's first law of motion says, "an object in motion stays in motion." He showed that, in a vacuum, all objects fall at the same speed, no matter how heavy they are. This means that heavy and light objects are not as different in how they fall as Aristotle thought.
Gravity for Everything: Newton introduced the idea of universal gravitation, which means that every object in the universe is pulled by gravity. He created a formula that explained this: . In simple terms, is the force of gravity between two objects, and are their masses, and is the distance between them. This idea helped people see that the same forces affect both the stars in the sky and the things on Earth.
Moving Away from Mystical Ideas: Newton shifted science away from mysterious beliefs and the idea that everything has a specific purpose. Instead, he emphasized using evidence we can observe and math to explain things. This change laid the groundwork for the scientific method we use today, which focuses on experiments and real observations rather than just thinking about ideas.
Influence on Future Scientists: Newton’s discoveries opened the door for future scientists like Einstein. He showed that science is always changing and that no idea is ever completely final. This encouraged people to question and improve what they knew about science.
In short, Newton didn't just improve scientific understanding; he also inspired people to ask more questions about the universe. This changed the way science developed moving forward.
