Final answer:
The principle of separation of powers divides the U.S. government into three branches (legislative, executive, judicial) to distribute authority and prevent the concentration of power, ensuring no single branch dominates governance.
Step-by-step explanation:
The goal of the principle of separation of powers is to prevent any one branch of government from becoming too powerful and ensure a balanced government. This is achieved by dividing the national government into three distinct branches: the legislative branch, responsible for making laws; the executive branch, responsible for enforcing laws; and the judicial branch, responsible for interpreting laws. Our Founding Fathers designed this system not only to distribute powers but also to create a system of checks and balances, where each branch has the authority to check the others, requiring them to cooperate in governing the nation.
For example, while Congress has the power to draft legislation, the president must sign the proposed legislation before it becomes a law. Additionally, the judiciary has the power to declare laws unconstitutional. These mechanisms are essential in preventing the accumulation of power within a single branch and promoting effective governance.
