Answer Posted / john rhoades
Gravity is the force by which all matter in the universe is attracted to all other matter. However, the strength of this attraction falls off according to the inverse-square law. That is, if something is twice as far away the power of gravity falls off to 1/4. Objects such as other planets are immensely further away from us than the center of the Earth. (The center of objects spherical is where you measure from. It takes calculus to work out why.)
All matter has a gravitational field equivalent to it's mass. That is, something twice as massive has twice the gravitational force. Additionally the amount matter is attracted by gravity is directly equivalent to it's mass. So big things are attracted more strongly to other big things. This is why you don't get pulled into other people or cars as they walk by. Not very big compared to the Earth or the Sun.
