As we all know, the fall of an apple from a tree is due to the gravity of the Earth. There are several different views on gravity. In the classical viewpoint, any object with a mass (e.g., the Earth) may produce a gravitational (GR) field. The presence of another object (e.g. an apple) in the GR field will experience a GR force (i.e. the gravity). In the view of Albert Einstein, any object with a mass will distort the spacetime. It is the curvature of the spacetime that gives rise to gravity. Since larger mass will produce greater distortion, heavier objects will exert stronger GR force.
