Students in the Extension Physics group are investigating the physics of bungee jumping prior to a trip to Lightwater Valley to experience amusement park and bungee physics for themselves.

We started looking at the equations used to determine the ‘spring’ constant and initial length needed so that neither extreme acceleration or hitting the ground occur:

We then used a simulation with springs and string, calculating the exact length needed so that a weight ‘just’ missed the floor:Â Energy calculations

See the video results below.
