Sweeping in front of the stone reduces friction and helps the curlers control the amount of curl the stone undergoes. The sweeping quickly heats and melts the pebbles on the ice leaving a film of water. This film reduces the friction between the stone and ice. The curling team is strategic in how much sweeping they do in front of each stone. If they want a stone to travel farther with less curl, they sweep more. If they want more curl or shorter travel, they do less sweeping.
The position of the sweepers is also strategic. The sweeper closer to the stone has more influence because the stone has more time to travel over the water film before it re-freezes. Curling is the only sport where you can change the direction of a projectile once it leaves the thrower's hand. Learn more about the science behind your favorite Olympic sports here!

The curling brush consists of a fibreglass or carbon fibre shaft with a fabric head used in a sweeping motion perpendicular to the path of the rock to clear debris from the ice and help maintain the trajectory of the stone.
Rocks are sensitive to the ice conditions and can pick up debris from the ice — known as a pick — which can veer the rock off course.
Sweepers will ease up with the hope the rock will lose speed. Sweepers will brush harder to attempt to drag the rock to the desired point.
The clock ticks down while the team is deciding which shot to make. Yes, they do. The World Curling Tour features tournaments all over the globe and runs roughly from August to the end of April.
Teams earn points toward a ranking system. Curling is considered a semi-professional sport with most curlers holding down full-time careers elsewhere. The best teams manage to juggle a job, working out at the gym, family time and being away for over a dozen or more weeks while on tour.
Yes and no. While it may appear some curlers are wearing normal pairs of kicks, they also wear different soles on their shoes: one for their sliding foot and a gripping sole on the other. They started wearing them during the Winter Olympics in Vancouver to stand out from the crowd. Clearly, it has worked. Throwing rocks at houses A curling ice sheet is roughly feet long by 15 feet, seven inches wide; about the length of a hockey rink with some room to spare.
How many players are on each team? Each team on the ice includes four players: lead, second, third and skip. Teams are typically named after the skip, e. AKA vice skip. Sweeps the first four stones.
Sweeps the first two stones. Sweeps the final four stones. Another common curling stone manufacturer is Thompson Rink Equipment. Note that when you purchase curling stones, they may come in sets of eight or 16, depending on the manufacturer. In general, the physics of curling hasn't been studied well but we do know that there is some friction between the curling stone and the ice. This friction acts as a source of heat, which melts a small layer of the pebble.
Since the front of the curling stone 'sees' the pebble first, it encounters a higher frictional force than the back of the curling stone. The additional friction at the front of the curling stones allows the back part to move faster. This frictional force differential creates a velocity differential, thus allowing the stone to move laterally. Since , curling stones used in the Olympics have been manufactured by Kays of Scotland, which come straight from the island of Ailsa Craig.
This means that no curler has used the curling stones before the Olympics begins. Having new curling stones for the Olympics helps ensure that the stones play as consistently as possible since they have not been used yet.
Before , the curling stones were produced by the Canada Curling Stone Company. Curling stones come in one color, gray, because that is the color of the granite that is used to produce all curling stones.
The curling stone handles, however, come in a variety of colors. While the most common colors are red and yellow, other colors such as blue and green can also be seen on a curling stone handle. On the curling stone handles, there may also be an engraving, which is painted a different color from the main color on the handle. Previous Next. Curling Stone. Table of Contents.
Curling Stone A curling stone is what is thrown by a curler during a game. Ailsa Craig Ailsa Craig is an island off the coast of Scotland and is one of the few places in which the granite used to make curling stones is mined. Dimensions The official dimensions of a curling stone are regulated by the World Curling Federation, the global governing body of the sport of curling.
Purchasing Stones Curling stones are usually sold in sets of eight or Stone Handles Curling stone handles are made of plastic and come in a variety of colors. Stone Price Typically, curling stones are sold in a set of enough for one sheet. Types of Curling Stones Since curling has become a rather standardized sport, there is only one type of curling stone used for play at most curling clubs and international competitions.
Stone Weight Generally speaking, curling stones weigh approximately 42 pounds. Trefor Granite Trefor granite is one of the types of granite that curling stones are made from. There is no definite weight of a curling stone, rather there is a maximum and minimum, between which it must weigh. The weight range is They also have a maximum circumference of the curling stone is According to CurlingStone.
