HomeinventionsWas Gravity Really Discovered by Einstein after a Fallen Apple? Isaac Newton and gravity Sir Isaac Newton and his scientific accomplishments and theories like gravity arguably started the scientific revolution. During his lifetime, between 1643 and 1727, he was able to master many fields of science. Having contributed to mathematics, physics, alchemy, astronomy, and philosophy, many do not realize he was also a theologian. Although he contributed many theories and his brilliance beyond his time, many scholars believe he seeded and perpetuated a silly story in order to be remembered through history. One of the biggest misconceptions is that he came to realize what is now known as the “gravity” after an apple fell on his head. Recently, documents have been released that explained it was not the apple falling on his head, rather, the apple falling straight to the ground that inspired these theories. He pondered, “What could have caused the apple to fall perpendicular to the earth?) He concluded that there is a force acting on a body of mass, and the force must be gravity and thus objects have “gravitational mass”. In addition, the acceleration of an object could be caused by any force, not just gravity, and thus objects must have ‘inertial mass”. He further concluded that if a gravitational force is applied to an object having both gravitational mass and inertial mass, its acceleration would be relative. This, along with the equivalency principle, was the foundation for the great works of Albert Einstein, shaping the course of physics to what it is today.
