THE REASON WHY UNSUPPORTED OBJECTS DON'T FLOAT AWAY IN SPACE IS BECAUSE OF GRAVITY. GRAVITY IS A FORCE THAT PULLS US TOWARDS THE CENTRE OF THE EARTH.

A MAN NAMED ISAAC NEWTON WAS THE FIRST PERSON TO REALLY STUDY GRAVITY. THERE IS A STORY THAT ONE DAY ISAAC WAS SITTING UNDER AN APPLE TREE AND THEN AN APPLE FELL ON HIS HEAD AND THEN HE STARTED TO WONDER WHY DID THE APPLE FALL DOWN AND NOT LEFT OR RIGHT. HE REALISED THERE WAS A SPECIAL FORCE PULLING IT TOWARDS THE GROUND. NEWTON ALSO REALISED IT DIDN'T MATTER HOW HEAVY AN OBJECT WAS IT WOULD STILL COME DOWN.

WHEN WE SAY UP OR DOWN WE DON'T MEAN IT IN THE SENSE THAT WE'RE USED TO . IF YOU SAID GRAVITY PULLS THINGS DOWN TO THE EARTH WE ACTUALLY MEAN GRAVITY PULLS THINGS TOWARDS THE EARTH AND IF YOU SAID UP IT WOULD ACTUALLY MEAN AWAY FROM THE EARTH

TO ESCAPE THE EARTHS GRAVITY YOU NEED TO REACH A SPEED CALLED ESCAPE VOLICITY. ONCE YOU'VE REACHED ESCAPE VOLOCITY YOU WILL BE GETTING FURTHER AWAY FROM THE EARTH. THE FURTHER AWAY YOU GET FROM THE EARTH THE LESS OF EARTHS GRAVITY YOU WILL FEEL AND THE MORE OF THE MOONS GRAVITY YOU WILL FEEL

THE EARTH HAS AN ATMOSPHERE, WHICH HAS THE JOB TO PULL THINGS TOWARDS THE EARTH. E.G AN ASTROID WHEN IT PASSES THE EARTH IF IT IS IN THE EARTHS ATMOSPHERE WE GET A CLEAR VIEW AT IT.
