Final answer:
When approaching turns or curves, riders should travel at an appropriate speed that allows them to maintain control and navigate safely. In racing, drivers take the inside path on curves to maintain high speeds. Bicyclists lean at the correct angle to maintain balance while turning.
Step-by-step explanation:
When approaching turns or curves, riders should travel at an appropriate speed that allows them to maintain control of their vehicle and navigate the curve safely.
In racing situations, race car drivers often take the inside path (called cutting the corner) when approaching a curve because it allows them to take the curve at the highest speed possible.
Bicyclists negotiating a turn on level ground must lean at the correct angle to ensure that the force of the ground on the wheel is on a line through the center of gravity. This process produces a relationship among the angle, the speed, and the radius of curvature of the turn.
