please give me an example of a number of joules per something (in human terms)
and any additional information would be welcome and appreciated

Work=force x distance = Nm
Nm (Newton Meter) is called a Joule an expression of a unit of energy.
Power is defined as the rate of doing work
Power=work/time
Power = J/s
Power at a rate of J/s is one watt (W)
A 60 watt lighbulb experessed as Joules/s would be 60 Joules of energy per second (J/s or W).

A joule is the result of 1 newton acting a distance of 1 meter.

an example i learned was the "paracardial thump". this equates to hitting someones chest who is unconscious to make them revive. 5 joules of force is required to do this. any more force would break a rib.
so just think about what it would take to break a rib with your fist, and thats prolly 6 joules or so.
