= Eötvös experiment
{wiki=Eötvös_experiment}
The Eötvös experiment, named after the Hungarian physicist Loránd Eötvös, is a fundamental experiment that tested the equivalence principle, which is a key component of Einstein's theory of general relativity. The equivalence principle states that gravitational mass (the mass that determines the strength of the gravitational force) and inertial mass (the mass that determines how an object accelerates when subjected to a force) are equivalent.
