Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are attracted to one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing and forming stars and caused the stars to group together into galaxies, so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become weaker as objects get further away. Gravity is most accurately described by the general theory of relativity, which describes gravity not as a force, but as a consequence of masses moving along geodesic lines in a curved spacetime caused by the uneven distribution of mass.
關於Gravity
Two astronauts leave their shuttle when it is completely destroyed by a horrible accident and now it is just them alone together in space trying to find a way back to Earth.
Gravity的成就
Alfonso Cuaron wrote and directed the film. The film won seven Academy Awards.
您不知道JGravity的熱門事實
Anti-gravity, the idea of neutralizing or repelling gravity.. Artificial gravity - Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation.. Gauss's law for gravity - In physics, Gauss's law for gravity, also known as Gauss's flux theorem for gravity, is a law of physics that is essentially equivalent to Newton's law of universal gravitation. It is named after Carl Friedrich Gauss.. Gravitational potential - In classical mechanics, the gravitational potential at a location is equal to the work per unit mass that would be needed to move an object to that location from a fixed reference location. It is analogous to the electric potential with mass playing the role of charge.. Gravitational wave - Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.. Micro-g environment, also called microgravity.. Empirical laws.. Acceleration.
