Euler forces result when these things rotate non-uniformly. Einstein's equivalence principle states that gravity and acceleration depend only on these things.  Galilean transformations convert between these things, as do "boosts" involving the Lorentz factor, when these are moving close to the speed of light. According to special relativity, none of these is absolute. Fictitious forces arise when these are accelerating; for example, a rotating one is responsible for the observed deflection of objects in the Coriolis effect. For 10 points, name these hypothetical coordinate systems used by observers in physics problems.
