The winter olympics sport of curling is one of immense proprtions relating to physics. As the stone is lightly rolled across the ice it is facing many forces. The force of gravity is pushing down as it makes it's way down the ice. There is the normal force on the stone making it stay on the ice at the same height. There is also the force of the stone being sent down the ice. There is also friction coming from the stone as it meets the ice causing it to slow down and land in the bulls eye. This is where physics comes into play in the sport of curling.
