Before "physics" was a formal word, it was natural philosophy. The goal was to find the "why" behind the physical world. and acceleration. By 1900

Einstein reimagined gravity. It’s not a "pull," but a curve in the fabric of space-time caused by mass. two massive shifts occurred.

Proposed that objects have a "natural place." He believed heavier objects fall faster—an idea that lasted 2,000 years.

He provided a mathematical framework for force, mass, and acceleration.

By 1900, physicists thought they had it all figured out. Then, two massive shifts occurred.
