probably the g-force, or gravity
when you jump, you experience weightlessness, in a sense, and your internal organs will pull or push towards your feet (if jumping headfirst) or back (if horizontal) but with a reduced pressure than from say, walking or standing around.
when you suddenly decelerate, the g-force is multiplied
a short explanation would be it's like the high speed start Roller Coasters or taking off in a jet, except in a different direction. So lets say you go face first: provided you don't eat dirt or concrete or whatever your jumping over, when you slow down, all of your body fluids and organs will go from a normal position (standing before a jump) to a neutral position (the moment in air where your jump-force or how high you jumped counteracts by a ratio of 100:100 with gravity and you are weightless for a few milliseconds) where your body and it's organs and fluids will be neutral in air and float randomly, to a slight pull towards your feet (magnitude depends on your velocity:when your begging to descend towards the earth) and finally a large pull on your organs and fluids from rapidly decelerating (this will be similar to if you were strapped on the hood of a car going 80 miles per hour and all of the sudden slammed on the brakes; it is not unpleasant to most, but if you can't stand to have the blood rush to your head, maybe bungee jumping isn't right for you)
the main force is gravity, that pulls the bungee ujumper to the ground and then air resiustance comes in which balances the jumper so she doesn't sink through the ground too the centre of the earth
1) Air Resistance 2) Friction from the rope?
gravity and a bit of air resistance

Gravity and elastic force.
When bungee jumping, people go head first because the bungee cord is attached to their feet, and if they reamined in an upright position until they reached the end of the cord, it would flip them upside down with a very large amount of force. This would create a painful whiplash and greatly increase the risk of injury to the jumper, especially in to their spine.
No, a bungee cord cannot be used as a force meter because the elasticity of a bungee cord is not that much, compared to a force meter.
Gravity, rope, and friction
Gravity and elastic force...
long time, small force
Bungee jumpers use ropes that have small values of the force constant because they want maximum stretching for their cords to preserve as much energy as possible from their initial fall. The units of force constant are N/m. On a bungee cord, you would like the stretch to takes as little force as possible per meter of cord.
The energy didn't "go" anywhere. It gets its energy from someone letting it go. It all depends on how much force you put on it.
well if they didnt have bungee rope then all of their weight would hit them at the same time. Whereas if you have a bungee rope then it lets you take your own weight very slowly

Potential long time, small force
Any force that originates above you does. It could be the tension in a bungee, in the harness of a parachute, etc.
