Why do astronauts float in the ISS?Image: The International Space Station (ISS) is placed in low Earth orbit, at an altitude of approximately 415 km, it circles the Earth in 90 minutes at a speed of 7.7 km/s or 27,700 km/h. The international crew, which is dedicated to scientific ...
Gravity constantly pulls things down when it enters the earth’s atmosphere. Why does earth have a gravitational pull? Earth’s have a gravitational pull that keeps us on the ground so we won’t float off in space. What is the earth’s atmosphere made of? earth’s atmosphere has 78% ox...
Why does the author provide the information that “It is much easier for an icy body to differentiate than for a rocky one”? A. To support the claim that all of the big icy moons are differentiated B. To suggest that Callisto may be a rocky body rather than an icy one C. To expla...
Does ice always float? Ice always floats because it is less dense than regular water. Because frozen water molecules form a crystal, they take up more space and have a lower density than regular liquid water. But keep in mind that ice might not always float in other fluids, like air, al...
Why does ice float, for example? It's fun to experiment with ice. If ice didn't float, life on earth would be impossible.Climate Change and the Floating MiracleHow come? A pond or lake's ice would sink to the bottom when it formed. If the ice didn't get sunlight, it would ...

The heavier you are, the steeper the sides of the trampoline well. That is why really massive things in the universe – like the Sun or black holes – have stronger gravity than Earth. So why does gravity pull you down and not push you away?
Why does the sun rise in the east and set in the west? Why is there centripetal force in space? Why is centripetal force inward? Why doesn't centrifugal force actually exist? Why are seasons important to Earth? Why is it summer in the Northern Hemisphere when it is winter in the Southe...
This is a great question. It comes up quite often. If you ask the people around you, there are two common answers: Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gra
