What fruit is associated with Isaac Newton’s theory of gravity?
Legend has it that in 1666, a 23-year-old Isaac Newton was sitting under an apple tree when an apple fell from the tree and boinked him in the head, resulting in a “Eureka” moment. Gravity! Following his apple insight, Newton presented his three laws of motion in “Mathematical Principles of Natural Philosophy,” which has been called the single most influential book on physics. Newton demonstrated that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits.
The correct answer is Apple.
