Answer:
Step-by-step explanation:
If we consider the Reformation as an action, then we must think of the context of the action. The Roman Catholic Church controlled religion life and had a strong hand on political life in 1500. The Emperor's ultimate authority came from God and the church, and religious unity was increasingly a key aspect of the emerging kingdoms.
When Luther proclaimed his thesis, he was challenging this status quo. Just as a force applied to an object at rest attempts to move it. He challenged the authority of the Pope over religious beliefs, but also the authority of the Emperor over political life. The force he applied soon found support, and the object started to move all over Europe, like an object sliding down a ramp, gaining momentum.
However, the Catholic Church and the Emperor would not let their authority slip without resistance. The Counter-Reformation used many of the tools Luther had used to try and counter his arguments. The Emperor suppressed movements and uprising and pursued the Reformers. Friction increased as the momentum of the moving object increased, slowing it and questioning its initial energy.
