what is the principle of isaac newton's law of gravity?

a change in motion is relative to the force acting upon it.

the force that pulls two objects toward each other depends on the mass of each object.

an object in a state of rest will remain in that state unless some force acts upon it.

for every action, there is an equal and opposite reaction.

after the roman empire, the catholic church began to unify by taking on many duties of a government.

the first 10 amendments to the u.s. constitution are known as the bill of rights. those 10 amendments establish the most basic freedoms for americans including the rights to worship how they want, speak how they want, and assembly and peaceably protest their government how they want. the amendments have also been subject to much interpretation since their adoption, particularly the right to carry a gun under the second amendment.

"a bill of rights is what the people are entitled to against every government on earth, general or particular, and what no just government should refuse, or rest on inference," said thomas jefferson, the author of the declaration of independence and the third president of the united states.
