Answer:
Drag, or atmospheric resistance, is one of the greatest enemies of athletes in the Olympic Winter Games. Drag is a kind of friction that opposes athletes' movements through the air and slows them down. However, drag doesn't just affect athletes; it acts on any object moving through the air. I’ve noticed the effects of drag on cars. Newer cars with aerodynamically shaped fronts are less affected by drag than older cars with large, flat fronts. An aerodynamic shape reduces the drag by curving the air around the body of the car. The same principle applies to other vehicles too. For motorbikes, airplanes, and even ships, engineers try to design a shape that will keep drag at a minimum.
Explanation:
Drag, also known as atmospheric resistance, is one of the most formidable adversaries of athletes competing in the Olympic Winter Games.
Drag, also known as air resistance, is a type of friction or fluid friction in fluid dynamics. It is a force that acts in the opposite direction of the relative motion of any object that moves in relation to a surrounding fluid.
Drag is caused by the velocity difference seen between solid object and a fluid. The motion must exist between the object and the fluid. There is no drag if there is no motion.
Thus, atmospheric resistance, also referred to as a drag force, is one of the most formidable opponents of Olympic Winter Games athletes.
