Application of Analogy Method in the Teaching of the Gravitational Field
By way of analogy,the Gauss theorem of electrostatic field and loop theorem to the Gauss theorem of gravitational field "and"loop theorem ",defined the gravitational field and the gravitational potential.The gravitational field of the"Gauss theorem"of the two kinds of special symmetric gravitational field and the force law of gravity, simplifies the integral operation;by the gravitational field of the earth"loop theorem"objects around the gravitational potential energy.
