You have a bh ... as you FREE FALL into the black hole, you are semi weightless, however as you get closer there is a difference in the pull, a gradient persey. So that you feer ( if you are falling feet first, are pulled faster than your head. The net effect that you notice is that your feet are being pulled away from your head ... or your head is being pulled away from your feet ...
the force is:
That is in the one direction ... BUT there is also something else that is going on, since there is a sphere of spacetime being collapsed into a circle ... the angle forces push inwards laterally. Like this
this is what I am calling fan in.
The best illustration I have seen of this is in black holes and time warps by thorne, page 104 in my book under the sub topic tidal gravity and spacetime curvature
Note: if you were falling straight down, OR if the BH is sooooo big that the there isnt much tidal forces, to the point that they could get ignored, then you would not have any lateral forces acting on the body. However for smaller black holes, the tidal forces are significant .. thus the spagettification
