Modify the variables to observe how energy is transferred between kinetic, gravitational potential and elastic potential during a bungee jump. The drop distance can be varied with the slider along the bottom, and the energy is shown by the thick coloured lines (and given as values). From the kinetic energy, speed can be calculated. From the elastic potential energy, tension can be calculated, and - combining this force with weight - the resultant acceleration can be found.
Note: lambda represents the modulus of elasticity (measured in Newtons), l is the natural length of the bungee cord (in metres), m is the mass of the jumper (in kilograms), g is the acceleration due to gravity (in metres per second per second), h is the height of the launch point above the ground (in metres) and u is the initial velocity (in metres per second).
