Proving something to be true or not!
Let's say you are trying to prove if something is true or not true. Take a look at this example first, before I explain something: My little brother wondered if an apple has its own gravitational pole. In order to PROVE that it is true or not, you had to look at something else that does HAVE a gravitational pole. And this object that does have a gravitational pole is the earth and other planets. We live on earth. Earth pulls us down by gravity, and we do not fall off. An apple is a lot smaller than earth, so to prove if an apple has its own gravitational pole, use one grain of rice or some other small object to prove if it stays on the apple or not. If you were to put a grain of rice on top of an apple and turn the apple upside down, the grain of rice would fall off. So an apple clearly does not have a gravitational pole! This is how you would PROVE that an apple does not have its own gravitational pole. END OF EXAMPLE So remember that whe...
