Impulse is measured by the force multiplied by the change in time. There is a lot going on with the puck. Forces are applied back and forth, and there are also transfers of momentum. It is definitely the lack of friction that allows the puck to zip across the table with such ease. This makes the game faster and more exciting.
Friction is the force that occurs when two surfaces are in contact with each other.
It slows down or even stops objects that are moving. There are two types of friction associated with Air Hockey. They are static and kinetic frictions. Static friction applies to friction between surfaces when the object is at rest. Kinetic friction has to do with the friction between surfaces while the object is in motion.
