No, a canon is not a type of catapult. A canon is a type of rule, principle, or accepted body of work, while a catapult is a device used to launch projectiles over a distance.
The scientific principles behind a catapult involve potential and kinetic energy. When the catapult is loaded with an object, it stores potential energy. As the catapult arm is released, the potential energy is converted into kinetic energy, propelling the object forward. The design of the catapult, including the leverage and tension mechanisms, determines the efficiency and distance of the launch.
The scientific principle is friction.... and heat and ultimately the FIRE
Archimedes is the Greek scientist who discovered the principle of the lever and invented the double pulley. He did not invent the catapult but he did improve it. He also discovered the when an object is place in fluid, the volume of the fluid that is displaced is equal to the volume of the object.
Bernoullis principle
No, a catapult works on the principle of stored mechanical energy that is released to propel an object. Frictional force plays a minimal role in the functioning of a catapult as the stored energy is primarily converted into kinetic energy for the launching of the object.
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.

Gravity.
None, by definition a superstition has no scientific principle.
