Final answer:
During a lock-up in Formula 1 racing, the wheels of the car stop rotating while turning on a corner due to a skid, where the tires lose traction with the road surface.
Step-by-step explanation:
During a lock-up in Formula 1 racing, the wheels of the car stop rotating while turning on a corner. This is due to the phenomenon known as a skid, where the tires lose traction with the road surface. When the tires skid, the frictional force between the tires and the road decreases, leading to a loss of rotation. The car continues to move in the direction of the skid, causing a loss of control and potentially compromising the race.
