When the gravitational Force hits the earths surface the gravitational pull has just the right amount of gravity. It helps us walk like we are spouses to walk and not just float in the air. witch means we walk like normal. It helps us even more because we can walk fast and when you are in the air you move slow.
when you drop something it goes straight to the ground and does not float in the air. this is called gravity. Gravity helps us stand straight and not flop around. witch is great because this help us not mess up any bones in our body.
in this picture you see that there is a shape and this shape helps us understand how gravity works. Gravity works by keeping us on the ground because if we weren't on the ground we would be in space by now. This works by this enviable line that goes threw the earth. If that line was not there we would be floating in the air.
this video is on how there is no gravity in space and on how we have gravity is on earth. The first thing i like to talk about is the one where there is no gravity in space. How you might be asking its because there is no oxygen up in space. The next thing is how gravity works on earth it work by that invisable line that goes through the earth
