How does science make bungee jumping possible?

Science makes bungee jumping possible through the principles of physics, particularly elasticity and energy conservation. The bungee cord is made from materials that can stretch significantly, allowing it to absorb the jumper's kinetic energy during free fall and then convert that energy back into motion as it recoils. This process ensures a safe and controlled rebound, preventing injury. Additionally, calculations related to gravity, velocity, and the jumper’s weight are essential to determine the appropriate cord length and elasticity for a safe experience.
