The stone gathers friction as it glides over these little ridges, which is why the athletes sweep away fairly hard at the ice -- it smooths down the path of the stone. Also, depending on which sweeper is giving more force, the iced-over droplets will smooth over in the direction of that particular sweeper. This causes the stone to alter it's course, rather than keeping a straight path.
So, in short, ice used for curling is not smooth. Tiny ridges and bumps contact the stone, slowing it down.
Any time you have two surfaces sliding against each other, you have friction. When a curling rock slides down the ice, the amount of friction determines how the rock acts: how quickly it slows down, and how much it curls (follows a curved path) as it travels down the ice. The friction that occurs when players sweep the ice in front of a rock with their brooms heats up the ice and creates a small film of water on top the ice, which reduces the friction between the rock and the ice. This makes the rock travel farther down the ice, and curl less.

Curling. A kettle is slid across the ice. Team members brush the ice in front of the kettle to minimize friction.
Skiing, bobsleding, snowboarding, curling, and much more
Low friction is slippery high friction has good traction. In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
Friction can slow down a rock and the speed of the rock depends on the force you exert.
A curling stone is designed to have very little friction with the ice, allowing it to travel long distances when pushed with enough force. The smooth, polished surface of the stone and the curling ice create a low-friction environment that helps it glide effortlessly across the ice. Additionally, the weight and shape of the stone provide stability, allowing it to maintain momentum and travel further.

In the sport of Curling (gliding those heavy granite stones on ice towards a bullseye) one shoe has low friction (to slide on the ice) the other has high friction (to propel the player).
The force of friction is a contact force. An example of a force at a distance would be gravity.
