Question

I'm desiging an experiment to prove energy loss of a system. We have an air track to use, 2 gliders and 2 photogates to measure times on the air tracks. The main task is to design an experiment that will measure the energy loss of the cart/glider on the track as it travels down and bounces back on a rubber band bumper. I'm planning on using a simple conservation of energy equation and calculating velocities using the times from the photogate, but need another independent method to prove energy loss and have no other ideas. Is there another good method to prove the energy loss that uses the materials we have?  I'm also trying to find a way to take into account a collisional loss of energy due to a bumper and it's inelasticity.  

Explanation / Answer

i dont think we have another good method. The method whic you are using is the best one.
