Gravity. The average person probably doesn’t think about it on a daily basis, but yet gravity affects our every move. Because of gravity, we fall down (not up), objects crash to the floor, and ...

en.wikipedia.org/wiki/Gravity_of_Earth

The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).. In SI units this acceleration is measured in metres per second squared (in symbols, m/s 2 or m·s −2) or equivalently in newtons per kilogram (N/kg or N·kg −1).

Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Albert ...

A new window on the universe: waves of gravity. The most promising clue to our cosmic origins may be the tiny gravity waves set in motion during the Big Bang itself. These ripples of gravity have eluded detection so far, but NASA aims to look for them with the LISA mission, to be launched in the next decade.

en.wikipedia.org/wiki/Defying_Gravity_(song)

Idina Menzel, having reprised her role as Elphaba in the London production of Wicked in 2006, recorded a remixed "pop mainstream" version of the song. It was released as a single on March 1, 2007, and was later included on the UK and iTunes versions of her 2008 album I Stand.The remix of "Defying Gravity" was also the anthem at the 2007 Gay Pride Parade and Festival in Los Ange...

Gravity, in mechanics, the universal force of attraction acting between all matter. It is by far the weakest force known in nature and thus plays no role in determining the internal properties of everyday matter. Yet, it also controls the trajectories of bodies in the universe and the structure of the whole cosmos.

Gravity Emerges from Quantum Information, Say Physicists. The new role that quantum information plays in gravity sets the scene for a dramatic unification of ideas in physics.

During the flyby Juno will come to within 347 miles (559 kilometers) of Earth. The Juno spacecraft was launched from Kennedy Space Center on August 5, 2011 toward Jupiter. Juno’s rocket, the Atlas 551, was only capable of giving Juno enough energy or speed to reach the asteroid belt, at which point the Sun’s gravity pulled Juno back toward ...

All it really does is repeat it. "It has energy because it's going to be affected by gravity." It loses all that energy when it reaches the bottom and cannot fall further, and resetting it allows it to fall again. But that's just an explanation of the question's problem- where does that energy come from? Objects can't move without energy.

On Earth, gravity gives weight to physical objects and causes the ocean tides. The force of Earth’s gravity is the result of the planets mass and density – 5.97237 × 1024 kg ( 1.31668×1025 ...
