The <Einstein equivalence principle> combines the <weak equivalence principle> with local Lorentz invariance and local position invariance of nongravitational experiments. In a sufficiently small freely falling laboratory, their results agree with <special relativity> independently of its location and velocity. The <strong equivalence principle> extends this claim to local gravitational experiments.
