It’s hard to claim the nuclear bombs were a major contributor to their surrender when Japan was trying to surrender before the first bomb dropped. What made the surrender difficult was the ally’s demand that the Japanese emperor be stripped of his power. This was a big ask at the time, since the emperor was directly tied into Japanese religion.

In addition to this, the American military were committing war crimes before the drop of the nuclear bombs. The American military was killing more japanese citizens in there multiple night time carpet bombing runs than they did with the nuclear bombs.

The nuclear bomb was not “to end the war” because the war was already over when Truman decided go ahead and use then. The nuclear bomb was to show the USSR our military capabilities to scare them once the war ended.

Yes, like you stopping to peddle your bike…

A simple force diagram and application of newton’s 2nd law predicts the bike should accelerate to the left while it’s velocity is towards the right. This means the bike should slow down.

As a high school physics teacher, if this is the hill you’re willing to die on, then you neither understood the content in your high school physics class nor your university physics class. Newton’s 2nd law is generally accurate in most scenarios even without simplifications.
