We're taught that when Moses brought down the tablets, he shattered the first set in a rage after witnessing his people worshipping the golden calf.
As soon as Moses came near the camp and saw the calf and the dancing, he became enraged; and he hurled the tablets from his hands and shattered them at the foot of the mountain. - Exodus 32:19
A new set was later created which were then successfully taught to the people.
My question is can we be sure the first set of tablets was the same as the second set of tablets? What I mean is do you think Hashem may have changed the laws on the second set upon realizing how quickly we'd revert to idolatry, even after witnessing the events we did? Possibly, the second set being more stern and encompassing more behaviors than the first?
I'm curious if any writings discussed this?
