Survival in our Universe!

Home, Sweet, Home What do you really know about the Earth and what it provides you? It is a ball of stone and metal covered with water, rocks, and dirt. It has a fluid core of iron. 70% of it is covered with water. It has an atmosphere of 80% N , 20% O, and small amounts of argon, CO2, and water vapor.

How does the Earth’s gravity and the moon’s gravity AND the Sun’s gravity, compare to the gravitational force of other planets?

Can you find your “Center of Gravity?” If everything were weightless, balance would be no problem. In order to balance, objects must be in danger of falling; in order to fall, there must be gravity to give them weight! On the moon, an object will have the same mass, but a different weight. It’s gravity is 1/6 that of Earth. Would it be easier to balance an object there?
