There are several involved. Perhaps the most significant is the conservation of energy.
The principle you are referring to is known as the Principle of Natural Order or the Principle of Uniformity. It states that the universe follows consistent and predictable patterns, allowing for scientific understanding and observation of natural phenomena.
A scientific principle or law.
The Exchange of Evidence Principle was postulated by Karl Popper, an Austrian-British philosopher of science. Popper's principle suggests that scientific theories should be testable and falsifiable through observation and experimentation.
The principle of falsifiability states that any theory or hypothesis being tested must be stated in a way that allows the possibility for disproving, rejecting or showing as inaccurate that theory or hypothesis through scientific methods, techniques and procedures. If you state a hypothesis that renders it immune to any attempts for rejecting it via scientific methods, then you have violated the falsifiability principle and such hypotheses or theories are scientifically non-viable. You must make predictions that allow your hypothesis to be shown as incorrect.

The scientific principle is friction.... and heat and ultimately the FIRE
Bernoullis principle
Since it is called "the Heisenberg Uncertainty Principle" it is neither a scientific law nor a theory. It is a principle.
yes
To be true a scientific principle must be theoretically explained and experimentally (and statistically) checked to be correct and repeatable.

None, by definition a superstition has no scientific principle.
