What can be said about the effect of speed on the stopping distance of a motorcycle compared to a car?

The correct choice highlights that motorcycles, like all vehicles, experience an increase in stopping distance at higher speeds. The physics behind this is based on the principles of momentum and braking. When a motorcycle travels at greater speeds, it possesses more momentum, requiring more time and distance to come to a complete stop when brakes are applied.

Additionally, while motorcycles are generally lighter than cars, they also have smaller contact patches with the road, which can affect their braking performance, particularly in emergency scenarios. Combining increased speed with factors such as road conditions and motorcycle physics means that the stopping distance can indeed be longer when traveling at higher speeds.

This understanding is crucial for riders, as it emphasizes the need for maintaining an appropriate speed, especially in built-up areas or when navigating complex traffic conditions, to compensate for longer stopping distances.
