How It Works

Bungee jumping

This thrill-seeking activity uses elasticity to store and release the energy of a fall


Bungee jumping is a classic extreme sport because it plays with the laws of physics. The jumper drops through the air without a parachute. With the added mass of the slack bungee cord beneath them, they pick up speed faster than a skydiver. The bungee cord is slack at first, but when they reach the end it starts to pull. As it stretches it stores elastic potential energy like a spring. This slows the bungee jumper until the upward pull of the cord matches the downward pull of gravity and they come to a momentary stop. At the bottom of the jump, the cord releases its energy, propelling the jumper back up.
