Understanding Physics by Isaac Asimov
is a great book on physics that covers a lot of topics.

The only thing that I can think of that generates 40,000+ volts is a stun gun. Somehow they use one or two nine volt batteries and convert that into 100,000+ volts.

Another quick question, do we have a measurement for the force of gravity? I was just curious how much force it takes for a black hole to suck in light and about how fast it sucks things in. For instance, humans get pulled down to earth at like 130MPH or so? how fast would I get pulled into a black hole?
There is no constant speed in which bodies fall to earth (unless acted upon an external force for example:wind resistance), however there is a constant acceleration(~9.81m/s/s) of falling bodies(in a frictionless environment )on earth.
