Clean sweep.This year you can watch brooms sweep and stones roll at the Winter Olympics. No, athletes won't be cleaning up after themselves, and the Rolling Stones Rolling Stones, English rock music group that rose to prominence in the mid-1960s and continues to exert great influence. Members have included singer Mick Jagger (Michael Phillip Jagger), 1943–; guitarists Brian Jones won't be on stage. Curling curling, winter sport, similar in principle to bowls and quoits (see horseshoe pitching), played on an ice court by teams of four. Each player hurls a squat, circular stone—weighing 38 lb (17. , a 400-year-old strategic game on ice using brooms and stones, makes its Olympic debut this year. The sport involves two teams of four players each. Each player slides two 20-kilogram (44-1b) granite stones toward a circle or "house," 3.7 meters (12 ft) in diameter. The game's object: to get as many stones as close to the house's center as possible. Getting the stone in scoring position In the sport of baseball, a baserunner is said to be in scoring position when he is on second or third base. The distinction between being on first base and second or third base is that a runner on first can usually only score if the batter hits an extra base hit, while a runner on can be tricky. That's when Newton's Second Law of Motion Noun 1. Newton's second law of motion - the rate of change of momentum is proportional to the imposed force and goes in the direction of the force Newton's second law, second law of motion comes into play: An external force on an object causes the object to accelerate in the direction of the force. (See SW 11/17/97.) A player releases the stone with a spin, which forces it to curl curl In mathematics, a differential operator that can be applied to a vector-valued function (or vector field) in order to measure its degree of local spinning. It consists of a combination of the function's first partial derivatives. or curve to the right or left. To help the stone reach its goal, two teammates sweep the ice in front of the stone. Sweeping produces a thin film of water over the ice, which reduces friction--so the stone slides easily across the ice. Result: The stone travels 2 to 3 meters (6 to 10 ft) more. Score! |
