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)

How bungee jumping work?
Gravity and elastic force.
Why go head first in bungee jumping?
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.
Can a bungee cord be used as a force meter?
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.
A bungee cord begins to exert an upward force on a falinig bungee jumper?
Gravity, rope, and friction
How does the extension of a rubber band affect bungee jumping?
Well, if you extend a rubber band, after a while tension begins to build up and the rubber band wants to retract (return to its original shape), same principle with a bungee jump, the band is extended to it's limit and wants to return.
Why do bungee jumpers use ropes that have small values of the force constant?
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.
How does a bungee jump work long answer?
Gravity and elastic force...
A man bungee jumps off a bridge and is brought to a rest by the stretched bungee cord this is an example of the following?
long time, small force
Why is it important that the ropes stretch during a bungee jump?
The rope stretching during a bungee jump helps to absorb and dampen the jumper's kinetic energy, reducing the impact force on the body when they reach the bottom of the jump. This stretching process also allows for a smoother deceleration, which is crucial for the jumper's safety and comfort.
What would happen if the bungee rope is not elastic but made of a material that cannot stretch?
If the bungee rope were made of a material that cannot stretch, it would not absorb the energy of the falling person. Instead of a smooth deceleration, the person would experience a sudden stop when the rope becomes taut, potentially causing severe injury or even death due to the abrupt force. The lack of elasticity would eliminate the characteristic rebound effect of bungee jumping, resulting in a dangerous and unmanageable drop.
A bungee cord begins to exert an upward force on a falling bungee jumperWhere did all the energy go?
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.
How is the stretching force utilized in bungee jumping?
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
