gravity keeps the people and the puck on the ground Could you give an example of an equation that would show this ?
yes rough ice does effect the speed of the puck in ice hockey. it makes the puck go slower then if it was smooth ice.

The term "puck-stopper"is just one of many names used to refer to the goal-keeper in hockey.
No you can't.
Gravity keeps the puck near the table.
False
Neglecting friction, if a puck is sliding at 2 m/s it will still be sliding at 2 m/s when it slides off the table. Immediately before hitting the floor, its velocity in the x-direction will still be 2 m/s but it will have accelerated to a y-velocity of approximately 6.4 m/s, yielding a total speed of 6.6 m/s.
Gravith pulls it down; table pushes it up.
A good air hockey table has a large smooth playing surface. It is surrounded by a rail that prevents the puck and mallet from leaving the table. Slots on both ends of the table serve as goals.
The force of air from the airholes on the puck, and the resultant force. A shear force (v). Velocity and acceleration forces, as well as gravity.

A hockey puck of mass m = 0.25 kg is tied to a string and is rotating horizontally in a circle of radius R = 1.0 m on top of a frictionless table. The string is passing through a hole in the center of the table with a mass of 1 kg hanging vertically downward below the table. If the 1 kg mass hanging below the table remains in equilibrium (at a fixed position) while the puck is rotating horizontally. Since the weight below the table remains in equilibrium, the tension in the rope must equal the weight suspended from it T = W = (1 kg) × (9.81 m/s2 ) = 9.81 N
yes and no, It depends on what type of friction. it has no friction with the table, but it does have friction from the air being pushed from beneath. What slows the puck down the most is air resistance
yes it will
No, you don't dribble a puck. You stickhandle with the puck.
yes, it just has less friction across the table from the air pushing up on the puck through the holes.
