YOU SAID:

n Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

INTO JAPANESE

nニュートン物理学、自由落下は、重力がそれに作用する唯一の力である物体のあらゆる動きです。重力が時空の曲率に減少する一般相対性理論の文脈では、自由落下している物体には力が作用していません。

n Newtonian physics, free fall, is any movement of an object where gravity is the only force acting on it. In the context of general relativity, where gravity decreases to the curvature of space-time, no force acts on a free-falling object.
