THE LAW OF UNIVERSAL GRAVITATION

Definition: The law of universal gravitation (law of gravity) is the force that attracts all objects to each other, due to mass.

The force of gravity is measured in Newtons, named after Isaac Newton. All though Newton did not descover gravity, he was the first to realize that gravity was everywhere. The law of gravity depends on how much the mass of an object is, and is affected by the distance in between the two objects being pulled together. If the two objects get further apart they have less gravity. If they get closer their gravity increases.  

 This apple falling from the tree shows how gravity on earth pulls things to the ground such as the apple. But, at the same time the apple pulls on earth and the tree but its gravity is not as massive due to the apples mass.

SO WHAT??? SECTION:

Why do we need to learn this? Funny question we are learning this, not only because it has to do with space earth and everything else.......... Its whats keeping us her on earth in the room, on the seat without gravity, well everyone would be floating around. I know that sounds cool but its not good. Our food would be flying all over the place just think, our bodies wouldnt be used to there being no gravity so we would allways get sick and when you throw up thats going eveywhere except where you want it to.
