How Does Speed Influence Time and Particle Decay in Einstein's Theory?

[Herman Trivilino]

Gravitational force is the gradient of the potential and is, in the Newtonian approximation, $\frac{GM}{r^2}$ which is equal to g at the Earth's surface.

That's the gravitational field, the force is $mg$.

Yes. I tend to speak a little fast and loose because there is no good pithy term for the force-per-unit-mass.
