Why The Earth Has A Gravitational Pull
Gravity was discovered 3 centuries ago by Sir Isaac Newton. A mathematician and physicist by profession, Newton discovered gravity sitting under a tree and observing falling apples. After further research, Newton discovered that gravity exists between all objects and that gravity is essential for normal life on earth as it helps us from floating away into space.
Gravity exists for many reasons; it keeps the earth rotating in its orbit and keeps it at a certain distance from the sun, keeping our planet at a perfect distance from the sun, preventing it from burning or freezing. Gravity also keeps everything on the earth, from keeping our rivers, lakes and sea water in place it also keeps the essential earths blanket in place that protects us from the sun’s harmful rays.
Astronauts that go into space do not really feel gravity; they float about in their space ships and weight quite different from what they might weigh on the earth. The higher we go, the more gravity exerts its pull on us, the reason why we feel a pull when we look down from a high building. The closer we get to the earth, the lesser the pull of gravity, the reason why formula one car’s are designed with a flat structure.Can’t get enough?
