Objects fall towards the Earth due to the gravitational force exerted by the Earth on them.

Newton’s observations of celestial motions and his logical reasoning led to the recognition of gravitational force as a fundamental force in nature, governing the motion of objects on both terrestrial and cosmic scales.

Newton’s conclusion established that gravitational force is a universal phenomenon, acting between all objects with mass, from celestial bodies like planets and stars to everyday objects on Earth.

Newton reasoned that if the Earth can attract an apple and the moon, then all objects in the universe must attract each other, leading to the concept of gravitational force between all objects.

Newton observed that all planets orbit around the Sun, suggesting the presence of a force between them, similar to the force between the Earth and the moon.
