1. The problem statement, all variables and given/known data Design an experiment to determine if momentum is conserved in an explosion interaction using an air track. I need to come up with the procedure for this experiment. 2. Relevant equations Not applicable. 3. The attempt at a solution I have decided to use two gliders that are both initially attached, but glide off in opposite directions after the "explosion". There are two photogates on either side of the explosive, which will measure the time it takes for the gliders to pass through. The problem I'm having is determining what I will use to cause the explosion, making the gliders glide off in opposite directions.
