All planets have gravity- Some more than Earth, some less. Other planets that are large enough do have air- but not made up of the same gasses as Earth.
Yes, gravity is present in a vacuum. If it weren't, planets wouldn't orbit the sun, moons wouldn't orbit planets ect.
Yes, gravity affects the air that we breathe. That is why it is harder to breathe when we go up high mountains. There is less air there. Without gravity, the air would float off into space, just as we would.
What they float in is not even thin air. It's nothing otherwise knows as 'space'. They stay there because there is no force to make them move out of where they are. The planets go in their stable orbits round the Sun, with their forward speed balanced by the Sun's gravity which makes them curve continuously towards the Sun.
Well Earth has many resources like oxygen there are many others too.
Planets is the natural satellite of some accountable size orbiting the star.
The effect of gravity does effect the planets. Gravity keeps the planets to the sun. Gravity works between any 2 objects. It's the attraction between planets and sun that keeps planets going around the sun otherwise they would keep going in a straight line.
hot air rising (less dense air), gravity. aero dynamics dont do much
People can only breathe on Earth because the atmosphere here contains the right amount of oxygen needed for human respiration. Other planets may have atmospheres with different compositions that do not support human life.
Beacuse earth has water air and Sun the moon has no air or no Sun or water only earth is a life planets the other planets are the same like moon they had no air or Sun and water
No, air resistance is not a form of gravity. Air resistance is a type of friction that acts on objects moving through the air, slowing them down. Gravity, on the other hand, is the force of attraction between objects with mass.
Gravity is important in the real world because it keeps our feet on the ground, holds the planets in their orbits around the sun, and affects the flow of water, air, and other natural processes on Earth. Without gravity, life as we know it would not be possible.
It doesn't. The force of gravity depends on the masses involved, and their distance. However, air resistance can introduce other forces, that counteract the force of gravity.
