Equivalence Principle (as an impression) (クリ)
In laboratory experiment, inertial force is something that we can control. In laboratory where thought experiments are done, we can control falling of an elevator. On the other hand, it can be said that gravity is beyond our reach. In other words, inertial force and gravity will be different things.
Even outside laboratory (whether within our reach or not), inertial force and gravity will be different thing.
