Final answer:
Good traction is essential for a motorcyclist to steer, maintain balance, and brake safely without falling, especially on slippery surfaces where control is paramount.
Step-by-step explanation:
The role played by good traction when a motorcyclist is driving on slippery surfaces is multifaceted. Good traction is critical because it enables the motorcyclist to steer without falling, helps the motorcyclist to maintain proper balance without falling, and allows the motorcycle to brake without falling. All these factors contribute to the safety and control of the motorcycle during its operation, particularly on slippery surfaces where the risk of losing control is higher.
When a motorcycle turns, as illustrated in physics, the force exerted by the ground must align through the center of gravity. The frictional force, parallel to the road surface, provides the necessary centripetal force for turning, while the vertical normal force balances the system's weight. On slippery surfaces, insufficient traction can lead to a loss of frictional force, increasing the likelihood of an accident. Therefore, maintaining good traction is imperative for safe riding conditions.
In summary, good traction ensures that the motorcycle can interact effectively with the road surface, enabling maneuvers such as steering and braking to be performed safely without the motorcycle slipping or the rider losing control.
