Title: Discussion of Inertial Mass and Gravitational Mass
Abstract: In physics,mass commonly refers to properties of matter,which have been shown experimentally to be equivalent: inertial mass and gravitational mass.Inertial mass and gravitational mass are not strictly distinguished in Newton's mechanics,but Newton's mechanics is based on the equivalency of these two kinds of mass.The equivalence is sometimes referred to as the Galilean equivalence principle or weak equivalence principle.Albert Einstein developed his general theory of relativity starting from the assumption that this correspondence between inertial and gravitational mass is not accidental.This article describes the performance and the difficulty of these two kinds of mass in Newton's mechanics,and then,discusses the union of inertial mass and gravitational mass in Einstein's general theory of relativity.The conclusion is that the equivalence needs to be confirmed by the general theory of relativity.
