Today I learned about the universe and Newton's law on gravity, Newton’s law states that every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

This means that the closer the objects are to each other the more they are attracted to each other. So I'll show an example. Lets imagine a car and Earth attracted to one-another. Thats why the car stays on the ground instead of the floating in the air. Another example of gravity at work is in this link below.
