Which force is happening during bungee jumping?

Answer 1

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)

Answer 2

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

Answer 3

1) Air Resistance 2) Friction from the rope?

Answer 4

gravity and a bit of air resistance
