what preamble goal is fulfilled when amendments are added to the constitution?

Answer 1

Here's the Preamble:'
"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

I see six goals here. Do you see them? Make a list of them for yourself.

Then scroll down here and read through the first ten amendments (Bill of Rights) and see what you find:
