First one is Lorentz factor

Second one is saying dv/dt=F=0... I dunno, it's a statement that's true.... (sum of forces goes to zero, acceleration goes to zero, which makes sense as F=ma, Newton's 2nd law...?)
Third one is superposition of states in a probability amplitude (?) function.

This is high school stuff 

 

Edit: the 2nd one is actually Newton's first law, an object in motion stays in motion unless external force acted on it. Law of inertia. I think the trick is first one is the main principle behind relativity, 2nd one is for classical mechanics, 3rd is for quantum mechanics.
