What are the forces acting on a bungee jumping?

What is the physics behind bungee jumping?

The tension force increases as the cord stretches and will eventually become greater than the force of gravity, causing a switch in direction. The acceleration is now upwards. When the cord reaches its full stretching potential, it retracts, which causes the bungee jumper to fling upwards.

Why do bungee cords break?

A bungee cord should never be stretched more than twice its resting length. 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.

What happens to a bungee rope if the force is too high?

Below a certain height, the spring force of the bungee cord pulling up on the jumper exceeds the force of gravity pulling down. In that range, even ignoring the air resistance, the fall slows down, and then starts to reverse, so the jumper heads back up.

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.

Why does a bungee jumper eventually stop moving?

When the rope tightens, it slows the bungee jumper’s fall. This is because the force of the rope reduces the speed of the jumper. … Eventually the jumper comes to a stop – the energy that was originally in the kinetic energy store of the jumper has all been transferred into the elastic potential energy store of the rope.

How much should you weigh to bungee jump?

Rules vary for different bungees, but the general minimum weight for bungee jumping is 35/40kg. The maximum weight again differs between sites but is generally around 145/150kg.

Does a bungee jump hurt?

Your neck is at risk during a bungee jump, and injury to it can range from mild to severe. The force on this fragile part of your body that connects your brain to your spinal cord during the final stage of the jump can be enough to strain your neck muscles, and cause pain and a temporary decrease in range of motion.

Is there a weight limit for bungy jumping?

Yes you can choose to do a solo or tandem bungy from the Auckland bridge. You can also choose to have a water touch or not. Hi Ryan, the maximum weight for the Auckland Bridge Bungy is 150kg.
