A Bungee Jumper Hangs From

Hi Callum,

The force used in coming back up in bungee jumping is due to the wrinkle of the elastic fibers in the bungee cord. Here'southward a simple explanation of the mechanics involved in a bungee jump.

When a person does a bungee jump, he would usually leap from a high place--which means he starts off with a large gravitational potential energy.

As he plummets downwards, the potential energy in his torso is being converted to kinetic energy--allowing him to increase his down velocity.

One time the bungee string (attached to the person's body) extends pass its rest length, it volition start exerting an upward force on the person's body--slowing him downwardly. This upward force increases every bit the bungee cord gets more stretched. In add-on, the extension of the bungee cord allows potential energy to be stored in information technology.

Finally, the person's body comes to a terminate, the kinetic energy in his trunk has converted to potential energy in the bungee cord. At this indicate, the fibers in the bungee cord are stretched and have stored a large amount of potential energy. The fibers so contract, and pull the person's body up.

The upwards force volition and so pull the person's trunk upwards to a certain pinnacle--which would exist lower than what he began with due to loss of free energy. Then, the person would fall over again, repeating the process of falling and rise--which is the most exciting apart of bungee jumping!
