The dependence of free fall acceleration on speed in the Schwarzschild spacetime is obtained. It is confirmed that gravitation mass coincides with inertial mass. 

Gravitational mass of the photons

It is shown that the gravitational and inertial masses of a photon or, indeed, of any body are equal. Motion past and free fall onto a center of gravitational attraction are considered.

Light bending effect and space curvature

The doubling of the gravitational light-bending effect, in comparison with Newton’s theoretical prediction, is explained by the space curvature.

Photon's Mass

The double deflection of a light ray near an attracting center, which was predicted by Einstein, is explained by the space curvature.

Gauge dependence and self-force from Galilean to Einsteinian free fall, compact stars falling into black holes, Hawking radiation and the Pisa tower at the general relativity centennial

Obviously, in Galilean physics, the universality of free fall implies an inertial frame, which in turns implies that the mass m of the falling body is omitted (because it is a test mass; put

Application of the Euler–Lagrange method in determination of the coordinate acceleration

In a recent comment published in this journal (2015 Eur. J. Phys. 36 038001), Khrapko derived the relationship between coordinate acceleration and coordinate speed for the case of radial motion in
