I have a question about a one dimensional collision lab done in class. We set up an air rail with two gliders..one at each end. Each glider had a rubber band bumper. We pushed them towards each other and they hit each other and bounced back some. We collected our data..see attachement.
The Attempt at a Solution
The question that goes along with this collision is - is this an elastic collision?
Looking at the data I would say no. I am confused however because perfectly elastic, inelastic and elastic collisons should not show a loss of momentum. So I think we must have done something really wrong when we collected our data. Any thoughts?
