Gravity
Well, it depends on what you mean. If you mean when they bungee jump, then it helps them not fall and it stretches to a distance there it will pull the bungee jumper up or to a certain height.
The three forces acting on the bungee jumper are gravity pulling the jumper downward, tension in the bungee cord pulling the jumper upward, and air resistance opposing the jumper's motion through the air.
Bungee jumpers typically reach speeds of around 50 to 60 miles per hour during free fall, which translates to approximately 73 to 88 feet per second. The exact speed can vary based on factors such as the jumper's weight, the height of the jump, and the elasticity of the bungee cord. As the jumper falls, they experience acceleration due to gravity until the bungee cord begins to stretch and decelerate their fall.

Before a bungee jumper jumps, they possess gravitational potential energy due to their height above the ground. This energy is calculated based on their mass and the height from which they are jumping. As they leap off, this potential energy is converted into kinetic energy as they fall, and eventually into elastic potential energy when the bungee cord stretches.
Jumper error. 99% of the time the reason the jumper dies or is injured is because they, the jumper caused a equipment failure or a misscalcualtion if it is a self bungee jump.

Gravity, rope, and friction
Yes, bungee jumping exemplifies Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. When a jumper leaps off a platform, they exert a downward force on the bungee cord, which in turn exerts an equal and opposite force upward, creating the tension that eventually slows and reverses the jumper's fall. This interaction continues as the jumper oscillates, demonstrating the principles of action and reaction in motion.
The key variables of a bungee jump include the bungee cord's elasticity, the jumper's weight, the height of the jump, and the length of the cord. The elasticity determines how much the cord stretches under the weight of the jumper, while the jumper's weight affects the force exerted during the fall. The height of the jump influences the potential energy converted to kinetic energy, and the cord length must be appropriately calibrated to ensure safety and provide the desired rebound effect. Each of these variables must be carefully considered to ensure a safe and enjoyable bungee jumping experience.
One should thoroughly research the equipment, safety measures and physical requirements involved before becoming a bungee jumper. Taking classes is recommended to avoid possible tragic consequences of being untrained.
