What is gravity? Find out about the balance between gravity and inertia that keeps the International Space Station in orbit. Learn why astronauts "float" in space and how the space shuttle has to slow down in order to come back to Earth.

this was a really bad video

if space shuttle those speed , internal might extremely unstable people insides all got sick , and satellites whether need to keep in high speed for orbit earth not fall and away from the track , kinds of conflicts become these explanations although might provide by nasa but i not able certain believe must accurate

hey guys ! can some 1 answer this is the gravitional force on earth serface ( 40.000 KM/h ) is same at higher lvl of earth or does it get less the higher we get for exp at 50,000 km on serfce or 100km .. thanx

He just explained that! It is falling but is also moving laterally at just the right speed to forever miss the earth as it falls. The moon is so far away that there is much less gravity, so the moon is falling at a much lower rate.(gravity decreases in proportion to the square of the distance--here on the surface we are 4000 miles from th center, the moon is about 240000miles away, so th gravity at the moon is about 4000mi/240000mi squared, or 1/3600 of a similar object at earths surface).

moon moves slow 3679.2 km/hr-2286.14889 mp/h around the earth and not falling, how is that?
-
what is gravity made of? particles? waves?

well done
