How sweeping affects curling stone speed and trajectory

sportingnews.com

Curling players sweep the ice to reduce friction, slightly melting it and allowing the stone to travel further and maintain speed. Sweeping creates friction that melts the ice, reducing resistance. Stopping sweeping slows the stone. Sweeping can also slightly curve the stone by creating an imbalance. This technique is a key scientific element of curling, influencing the stone's speed and trajectory during play at the 2026 Winter Olympics.
