Have just started to learn general relativity. But I am encountering a problem.
The formula
Fgrav= -m ∇ φ (xB)
represents the gravitational force derived form potential.
Here, xB is B position, and φ(x) is the gravitational potential produced by A.
But I can't just understand the formula and what is ∇ in here.
Please help...
