+ Altitude, High altitude and low air pressure: Aviation :: Physical geography
  * At high altitude, atmospheric pressure is lower than that at sea level. This is because of two effects. These effects are gravity and the heat in the air. Gravity makes the air to be as close as possible to the ground. The amount of heat in the air makes the molecules move quickly and push against each other. This makes the air expand. So most of the air will be in the lower atmosphere, closer to sea level, and all the air pushing against each other is called air pressure. So air pressure is less the higher you go.
+ Black hole, History: Stars :: Astrophysics
  * In 1783, an English geologist named John Mitchell wrote that it might be possible for something to be so big and heavy that the escape speed from its gravity is equal to the speed of light. Gravity gets stronger as something gets bigger or more massive. For a small thing, like a rocket, to escape from a larger thing, like Earth, it has to escape the pull of our gravity or it will fall back. The speed that it must travel upward to get away from Earth's gravity is called escape velocity. John Mitchell thought it was possible for something to be so big that the escape velocity would be faster than the speed of light, so even light could not escape.
+ Erosion, Erosion by gravity
  * Gravity erosion is the simplest kind of erosion. Gravity simply pulls loose earth materials downhill. Landslides are dramatic examples of gravity erosion.
+ Force, Newton's Second Law, Weight
  * Gravity is a force. Everything that weighs something is being pulled by gravity.
+ Fundamental force
+ Galaxy
  * Gravity holds galaxies together, against the general expansion of the universe. In effect, the expansion of the universe takes place between groups of galaxies, not inside those groups. This is because the mass within a galaxy holds the galaxy together, and the same applies to the groups of galaxies, such as our Local Group. The gravitation is produced by the matter and energy in a galaxy or group of galaxies. Everything in a galaxy moves around a centre, and that is also an effect of gravity.
+ Galaxy, Description
  * Within galaxy clusters, galaxies move relative to other galaxies. They can and do collide. When this happens, the stars generally move past each other, but gas clouds and dust interact, and can form a burst of new stars. Gravity pulls both galaxies into somewhat new shapes, formng bars, rings or tail-like structures.
+ Gravity, Everyday gravity, Weight vs mass: Force :: Basic physics ideas
  * The Earth has mass. Every particle of matter has mass. So the Earth pulls on every object and person and they pull on the Earth. Gravity pulls on the mass and gives it weight
  - General relativity, Gravitational time dilation and frequency shift
+ Isaac Newton, Early life, Early workings: 1643 births :: 1727 deaths :: English mathematicians :: English physicists :: English science writers :: Fellows of the Royal Society :: People buried in Westminster Abbey :: People from Lincolnshire :: Presidents of the Royal Society
  * He described laws of motion and gravitation. These laws are math formulas that explain how objects move when a force acts on them. Isaac published his most famous book, Principia, in 1687 while he was a mathematics professor at Trinity College, Cambridge. In the Principia, Isaac explained three basic laws that govern the way objects move. He then described his idea, or theory, about gravity. Gravity is the force that causes things to fall down. If a pencil fell off a desk, it will land on the floor, not the ceiling. In his book Isaac also used his laws to show that the planets revolve around the suns in orbits that are oval, not round.
+ Surface tension, Effects in everyday life, Water: Basic physics ideas‏‎ :: Fluid mechanics
  * Formation of drops occurs when a mass of liquid is stretched. The animation shows water adhering to the faucet gaining mass until it is stretched to a point where the surface tension can no longer bind it to the faucet. It then separates and surface tension forms the drop into a sphere. If a stream of water were running from the faucet, the stream would break up into drops during its fall. Gravity stretches the stream, then surface tension pinches it into spheres.
+ Universe, Basic data on the Universe: Reality
  * The universe seems to have much more matter than antimatter. The Universe appears to have no net electric charge. Gravity is the dominant interaction at cosmological distances. The Universe also seems to have no net momentum or angular momentum. The absence of net charge and momentum is expected if the universe is finite. Landau and Lifshitz 1975.
