Mercury gravitational pull
Mercury is a planet of extremes. The side of the planet that faces the sun reaches a temperature of about 430°C (more than enough to melt lead), while the dark side is a frigid –170°. Mercury revolves around the sun every 88 days, and has the unusual characteristic of rotating on its axis exactly three…

Hands on the ground, NOW! Comment by Sakkura Should be useful for gathering mobs together. Comment by rasse667 HAIL! Comment by Idocreating Sup-par dps item. These are tanking gloves. Can be seen due to less Strength than heroic dungeon blues. Comment by monkiy Even with less Strength, I d think they…
Discovery of Dark energy
In 1998, two teams of astronomers discovered that, instead of slowing down, the universe is expanding faster today than it was in earlier epochs Adam Riess Adam Riess thought there must have been a mistake. In late 1997, he was analyzing observations of exploding stars to help determine whether the universe…

About gravitational force
a second body outside the sphere as if all the spherically distributed mass were contained in a point at the centre of the sphere. Thus, the attraction of the planets by the Sun was the same as the gravitational force attracting objects to Earth. Newton further concluded that the force of attraction…

Law Science definition
A law in science is a generalized rule to explain a body of observations in the form of a verbal or mathematical statement. Scientific laws imply a cause and effect between the observed elements and must always apply under the same conditions. In order to be a scientific law, a statement must describe…

Gravitational Fields
To begin with, the speed of gravity has not been measured directly in the laboratory—the gravitational interaction is too weak, and such an experiment is beyond present technological capabilities. The speed of gravity must therefore be deduced from astronomical observations, and the answer depends…

Formula for gravitational pull
The water above receives energy as it falls down the short waterfall. This energy was stored as potential energy in the gravitational field of the Earth and came out of storage as the water dropped. This energy which came out of the gravitational field ended up being expressed as the kinetic energy of the water. That is, the water gains kinetic energy as it drops. An ounce…

Earth gravitational constant
Laser range observations taken on the near-earth satellites of Lageos (a = 1.92 e.r.), Starlette (a = 1.15 e.r.), BE-C (a = 1.18 e.r.) and Geos-3 (a = 1.13 e.r.), have been combined to determine an improved value of the geocentric gravitational constant (GM). The value of GM is 398600.61 km³/sec², based upon a speed of light, c, of 299792.5 km/sec. Using the IAG adopted value…
