Discovering the Gravitational Force

Sir Isaac Newton discovered the force of gravity by observing an apple fall from a tree.

Newton observed that the apple fell vertically downward, leading him to infer that the Earth must exert an attractive force directed towards its center.

Newton questioned this to understand the nature of the force causing objects to fall towards the Earth.
