What forces are involved in bungee jumping?
The first force that the bungee jumper experiences is gravity, which pulls down on everything and makes the jumper fall. The gravitational force is almost exactly constant throughout the jump. During the bungee jumper’s fall, he or she also experiences a force due to air resistance.
What happens to your body when you bungee jump?
The extreme forces your body is subject to as it is pulled back upward by the bungee cord can injure the vertebrae of your spine and the delicate spinal cord that they protect. Injuries typically include compression fractures — broken bones in the spine — and herniated discs and spaces between the vertebrae.
Can a bungee cord break?
Even with normal use, bungee cords will eventually stretch permanently, fray, or break as exposure to sun, rain, wind, and extreme temperatures can accelerate a cord’s deterioration.
How does weight affect bungee jumping?
Gravitational forces exerted on the body during bungee jumping are reduced thanks to the elasticity of the bungee cord. For example, if a person weighing 100 pounds voluntarily leaps off of a building and experiences 900 lbs of deceleration force, they will experience 9 “G’s” of force.
How fast do you fall when you bungee jump?
Between about 2.5 seconds and 4.5 seconds, the jumper is freely falling and the acceleration is near – 9.8 m/s2. When all of the slack is out of the bungee cord, the acceleration begins to change. As the bungee cord stretches, it exerts an upward force on the jumper.
How is the person jumping fastened to the bungee cord?
The bungee cord is attached to a specially made ankle harness. The bungee jumper is now securely attached to the stationary object. Although a number of bungee jumping purists deride the use of a backup body harness, commercial bungee jump operators and those just recently introduced to the sport insist on using them.
What happens at the end of a bungee jump?
The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the kinetic energy is dissipated.
Can you bungee jump when pregnant?
Bungee jumping unfortunately is not recommended for women who are pregnant. Health requirements: Generally the participant must be in good health, if you suffer with epilepsy, joint problems or heart disease you may not be allowed to participate.
