This is achieved with a 200% stretch, (maximum length of the bungee line is 300% the original length). The free-fall of the jumper (while the bungee cord is still relaxed) The … The tension force increases as the cord stretches and will eventually become greater than the force of gravity, causing a switch in direction. When the jumper is experiencing free-fall, the only force acting on them is gravity. A bungee rope is specifically designed and its spring constant is known. Bungee jumping turns out to be more complicated than I realized. The gravitational force is almost exactly constant throughout the jump. Table Contents 1. Such as energy, momentum, gravity, forces and resistance. When a person does a bungee jump, he would usually jump from a high place--which means he starts off with a large gravitational potential energy. So why doesn’t the jumper just keep bouncing around forever? Once the tension decreases sufficiently enough that the force of gravity is greater once again, the jumper will repeat the full process, beginning with the free-fall. While modern bungee jumping has become known and practiced worldwide, what is less understood is the physics behind bungee jumping. 29 247-8. The Physics Teacher November 1993 Volume 31/Number 8 .
