WebFree fall. In 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. An object in the technical sense of the term "free fall" may not necessarily be falling ... WebIf an object falls through a vacuum without being slowed down by a drag force, its velocity v in m/s is given by the equation: v = √ (2gh) where g is the acceleration due to gravity. and h is the distance fallen in metres (m) In terms of time t in seconds since the object was dropped, another equation for velocity is:
