<span>The most important difference was that the Articles of Confederation gave very little power to a central government while the Constitution created a strong central government.
Other major differences include:
Articles of Confederation:
- no Bill of Rights
- gov't has no power to collect tax
- to make amendment, vote of states had to be unanimous
- no president (executive branch)
- only one "house" in Congress (unicameral)
- states could coin there own $ (so there were multiple currencies)
- Congress had between 2 and 7 reps per state
- representatives in Congress were appointed by state legislature (no popular vote)
U.S. Constitution:
- Bill of Rights
- gov't can collect tax
- amendment needs 3/4 vote
- has an executive branch
- two houses in Congress (bicameral)
- only U.S. gov't can coin $ (one currency for nation)
- Congress has 2 senators per state and representatives depending on the size of the state's population
- senators appointed, but representatives elected through popular vote</span>
The four of them made great contributions to the scientific world.
1. The scientist Nicolaus Copernicus proposed that the world revolved around the sun, the Earth included.
Even though his idea was not fully developed, it formed the foundation for future scientific improvements on planetary motion.
2. The astronomer Johannes Kepler proposed three important laws of planetary motion. Among these laws, he explained that planets move around the sun in an elliptical order.
These three laws contributed to the formulation of Newton's law of gravitation.
3. One of the main contribution that he physician Galileo Galilei was the law of the falling bodies.
It helped to comprehend that the force of gravity is constant and that it produces a constant acceleration effect in the falling bodies.
4. The physician Isaac Newton introduced the law of universal gravitation.
It states that there is a force that makes every particle in the universe attract each other.

The main way in which the Constitution overcame the weaknesses of the Articles of Confederation was that it made the central government much stronger by giving a great deal of power to the legislative branch, which now had power to make laws that could overcome individual state laws.
