How can a rubber band model elastic energy?

You can treat the rubber band as a spring. Ve=1/2*k*x2Where Ve is the elastic potential energy stored in the rubber band, k is the spring constant for the rubber band (can be calculated experimentally), and x is the distance the rubber band is stretched.


What would you need to do to a rubber band to increase its elastic potential energy?

Stretch the rubber band.


How does the elastic rebound the transfer of energy?
