Final answer:
Proper execution of a turn involves balancing centripetal forces by leaning at the correct angle so that the forces exerted by the ground align with the center of gravity, leading to a stable and controlled turn.
Step-by-step explanation:
If the approach and beginning of a turn are done correctly, the dynamics of centripetal force will be properly managed to maintain stability and control. When negotiating a turn on level ground, such as a bicyclist does, the ability to lean at the correct angle becomes instinctive. The vital aspect is that the force exerted by the ground must be on a line going through the center of gravity. When broken down, the force on the wheel can be resolved into two perpendicular components - with the vertical component cancelling out the weight of the system and the horizontal component providing the centripetal force that keeps the cyclist or vehicle on the turn's path. This balance of forces and the precise leaning angle yield a stable turn, ensuring stability and a successful maneuver through the curve.
