Perhaps I could back that up with a simplified version? Parakorn, have a look at the depiction of gravitational potential:
The curvature you can see in the depiction relates to the Riemann curvature tensor. But things don't actually fall down because of this. The force of gravity is denoted by the degree of slope, the first derivative of potential. The tidal force or Riemann curvature tensor is denoted by the change in slope, the second derivative of potential.
