What was the turning point in the discovery of the universal law of gravitation?2 marksMoon's accelerationNewton's intuitionEarth's attraction to objectsApple's fall
Solution
The turning point in the discovery of the universal law of gravitation was Newton's intuition. This came about when he observed an apple falling from a tree. He began to wonder why the apple fell straight down and not sideways or upwards. This led him to the idea that there must be a force (which he later named gravity) that acts between all objects in the universe. This force pulls them towards each other, and the strength of this force depends on the mass of the objects and the distance between them. This was a revolutionary idea at the time and marked a turning point in our understanding of the universe.
