all friction slows down movement
sliding friction slows down a sliding object

drag, which is a specific type of friction.
Two thing slow the balloon down. First, air friction opposes its upward movement. Second, as the balloon gets higher, the air around it gets less dense, so there's not as much force propelling the balloon upward.
Friction can stop an object in motion eventually. Friction causes drag on the object's motion energy and slows the object down by transferring the energy from one type to another. When the energy which acted on the object to put the object in motion is fully transferred, the object's motion will stop in the direction the motion and friction are applied. An example of this type of friction is the brake on a car. Friction can, however cause the object to change the direction of motion and simply stop affecting the object afterward. An example of this type of friction is the bumper rail of a pool table.

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

The kinetic energy of the object changes into thermal energy.
If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.
In any type of movement there is friction. This must be accounted for.
Brakes are used to slow down roller coasters. The brakes simply contract together against part of the car and friction brings them to a halt. Another type of roller coaster brake are magnets. The magnets have a force between them that slows the car down.
