Pucks and Collision

posted by Mel

If an experiment is being conducted with two pucks on an air table, an elastic collision. Does the pressure of the hose connected to the pucks effect the results of momentum and kinetic energy loss?

I think it may cause a minimal error on the collsion of pucks.

Yes there is some effect. You need a minumum air flow to create a cushion of air and greatly reduce friction. After you exceed some threshold air pressure and flow rate, further increasses shodl not make much difference in your results.
