Heya mate....

Answer 2

Answer:

Throw a ball in the air and gravity pulls it straight back down. Not everything moves like this when gravity acts on it. Most objects are not nice, neat shapes like balls. That means gravity acts on them in more complex ways. Even so, all objects behave as though their mass (the stuff they're made from) is concentrated at a point called their centre of gravity. A simple object like a ball has its centre of gravity in a very obvious place: right at its centre. But in a more complex object, like your body, the centre of gravity is slightly higher than your waist because there's more weight in the top half of your body than in the bottom half.
