WebFeb 15, 2012 · Gravity causes every object to pull every other object toward it. Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what … WebFeb 17, 2024 · Nature defines zero gravity as "a state of weightlessness," which is what happens when a spacecraft's acceleration counterbalances (and effectively cancels out) Earth's gravity. On paper, this sounds fun — but in practice for long periods of time, it's dangerous and even lethal to human health.

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.
