The first and third are intuitive observations to the point students should be aware of them even if they haven’t given them much thought before. The second might require a bit more consideration but even then it’s easy to point out how heavier things take more force to move as a simple example.
Coming up with some of the formulas in Physics by yourself would be hard but at least for kinematics it’s easy to observe relationships. You’ve already been using their ideas your whole life, you just start describing what’s involved in what you see and do all the time.
