What did galileo's principle of inertia state? not all heavenly bodies revolve around earth. the universe is centered around the sun, not earth. an object that is moving will keep moving until something stops it. an object that is moving needs something to keep it moving.

An object that is moving will keep moving until something stops it.

Explanation:

Galileo stated that: "A body moving on a flat surface will continue in the same direction and at constant speed unless disturbed."  Although nowadays velocity is usually referred to as a vector, in Galileo's time it was still a scalar, and therefore he believed that a uniform circular motion was natural, and that a body in such motion would continue to have it until a force disturbed him.

This argument served to explain the movement of the earth around the sun, since the force of gravity came only later, with Newton. It was also with Newton that speed was written as a vector, and the principle now has the current interpretation.

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
